Abstract: The hydro-geological survey and research in 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.

Keywords:: engineering investigation, hydrogeological, geotechnical, hazardous

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.
