Engine
ering has a very
important position, this paper describes engineering geological evaluation of the
content of hydro-geological exploration, soil hydraulic properties, groundwater
hazards caused by issues such as geotechnical engineering.

An engineering geological investigation in the evaluation of the content
of hydrogeological


In engineering exploration, evaluation of hydrogeological problems
should primarily consider the following:


1.
1 The evaluation should focus on rock and soil and groundwater on the role and
impact of buildings, predict possible geotechnical hazards, proposed control
measures.


1.
2
Engine
ering Investigation should also be closely based on the type of building
foundation needs to identify issues related to hydrogeology, to provide the
necessary hydrogeological data selection.


1.
3 from an engineering perspective, according to the role of groundwater and the
impact of the project proposed under different conditions, the evaluation should
be focused on geological problems, such as: buried in the ground water level on
the basis of the following buildings in the water on the concrete and the corrosion
of rebar in concrete. The selection of soft rock, weathered rock, residual soil,
expansive soil and other rock and soil bearing layer as a basis for the construction
site, should focus on the evaluation of the activities of the rock and soil water
potential softening, disintegration, expansion and contraction, etc. effect. In the

range of memory compression layer of foundation in loose saturated fine sand,
silt on, should have potential erosion forecast, quicksand, the possibility of piping.
When the basis of the lower confined aquifer exists, excavation should pressure
water washed away after the pit floor to calculate and evaluate the possibility.
excavation pit in the ground water level the following should be carried out
infiltration and water-rich test, and evaluation of the artificial precipitation
caused soil settlement, slope instability and thus the possibility of stability of
surrounding buildings.

2 soil hydraulic properties


Soil hydraulic properties is the interaction between rock and groundwater who
displayed a variety of nature. Soil hydraulic properties and physical properties of
rock are rock: rock and soil hydraulic properties affects not only the strength and
deformation of rock and some nature has a direct impact on the stability of the
building. In the past the investigation of physical and mechanical properties of
the soil test more emphasis on the geotechnical properties of the water
management has been neglected, and therefore the evaluation of the geotechnical
engineering geology is not comprehensive enough. geotechnical soil water and
groundwater management is the nature of the nature of the interaction shown,
first of all introduce the following form and occurrence of groundwater on soil
hydraulic properties, and then a few of geotechnical important water
management research
and testing methods of the nature and brief.


2.1 Occurrence in the form of groundwater: groundwater according to their
occurrence in the rock can be divided into bound water, capillary water and
gravity water three, which combined with water can be divided into strong and
weak bound water bound water two.


2.2 The major soil hydraulic properties and test methods: softening refers to the
rock mass after immersion in water, characteristics of the mechanical strength
decreases, the general said with the softening coefficient, which is to determine
the rock resistance to weathering, resistance to flooding capacity indicators.
There is easy in the rock layers to soften rocks, in the role of groundwater will
often form soft interlayer. all kinds of causes of viscous upper mudstone, shale,
argillaceous sandstone Dengjun widespread softening property. permeable, is
water under gravity, ground to allow water through their own performance. loose
rock particles became smaller, more uniform, its permeability will be weaker.
hard rock fissures or karst more development, the stronger its permeability.

permeable permeability coefficient of generally available, said upper body rock
permeability coefficient of struck by pumping tests.


disintegration, is soaking wet rocks, due to soil particles connections are
weakened, damaged, open to soil collapse and disintegration properties. to the
water, is fed by gravity from the pore water, soil, fracture properties of the water
must flow freely to the degree that water. water level is several important aquifer
hydrogeologic parameters also affect the venue sparse time. water level usually
determined by laboratory. expansion and shrinkage, refers to rock After the
volume of soil water increases, water loss volume was reduced after the
characteristics of the sizing of rock is due to thickening of the particle surface
adsorbed water absorbent, water loss due to thinning.

3 geotechnical hazards caused by groundwater


Geotechnical hazards caused by groundwater, mainly due to changes in
groundwater level and ground lift effect of the hydrodynamic pressure caused by
two reasons.


3.
1 Groundwater level change caused by the geotechnical hazards. Groundwater
level changes can be caused by natural factors or human factors, but for whatever
reason, when the groundwater level changes up to a certain extent, will cause
harm to the geotechnical engineering, groundwater level changes cause harm can
be divided into three ways:

3.
1.1 The water level rise caused by the geotechnical hazards. Phreatic reasons for
the increase are varied, the main aquifer affected by factors such as geological
structure, lithology general occurrence, hydrological and meteorological factors
such as rainfall, temperature, etc. and human factors such as irrigation,
construction and other effects, it is sometimes combined result of several factors.
As the water table rise may result in the geotechnical engineering: soil swamping,
salinization, soil and groundwater enhanced corrosion of buildings. slopes, river
rock and other rock and soil slippage, landslides and other geological phenomena
bad. some of the rock and soil with special structural damage, lower intensity,
softening. caused saturated fine sand and silt liquefaction, there quicksand,
piping and so on. flooded underground cavern filled with water, basic floating,
unstable buildings.


3.
1.2 caused by falling water tables, geotechnical hazards. groundwater bit more
than the decrease is due to human factors, such as the concentration of a large
number of extraction of groundwater. Deposits in the mining and upstream
