Based on the geological environmental conditions of evaluation area and the characteristics of the proposed construction project,the type of geological hazard which might induces or aggravates is predicted during or after the construction of the project;
Based on the complexity of geological environmental conditions of power station in southwest mountain,harmfulness of historical disaster,geological environmental conditions and the degree of injured bodies to undertake disaster are selected as basic factors and 16 relevant factors are selected to act as evaluating factors,fuzzy comprehensive evaluation-estimation is used to evaluate geological hazard of power station in southwest mountain and the trend of the geological hazard is predicted.
The engineering geological environmental conditions of the stone material exploitation areas are analysed,the main types of the environmental engineering geological problems(EEGP) caused by the stone material exploitation are studied,and proposals of prevention and control for EEGP are also proposed in the paper.
Based on the analysis of geomorphologic features shown on the aero photo taken before “7.13” landslide, site investigation of paleo-landslide remnant and geological environmental conditions for landslide developing it is deduced that Qianjiangping slope was a fossil landslide showing winnow shape before “7.13” landslide occurred.
According to the synthesis information of geological environment condition and the data determined by isotope tracer and natural tracer analysis that include hydrogeochemistry condition of Beijiang river dyke leakage, the reason of leakage and infiltration distortion of the dyke in the past years is the existence of some concentrated seepage passageways in the rock.
The crackings on buildings in research areas are the result of multi-factors comprehensive action,buildings open fissure relation to the geological environment condition of the research area,such as regional stability,hydrogeologic condition,engineering geological condition,structure of building,exploitation shaking of gold ore,etc.
According to geological environment condition,distribution and occurring rule of geological hazards,combining with economy loss caused by geological hazards,geological hazards areas in Shandong province can be divided into 7 subareas and 26 sections(land subsidence disaster,land crack disaster,surface collapse disaster,karst collapse disaster,disaster of avalanche,landslide and mud-rock flow,disaster of avalanche and mud-rock flow,sea water and salt water intrusive disaster).
According to the special geo-environmental condition and the current situation of geologic hazards control of the main mining cities in Liaoning Province,the article analyzes the main types and harm of geologic hazards induced by coal mining,discusses the measures to prevent and control geologic hazards and makes the planning suggestion for urban geo-environment protection and sustainable development.
The predication on the danger of geo - hazards in the mined - out area is carried out with the methods of engineering geological analysis, high density resistivity and half - quantitative respectively after the analyzing the geo - environment condition and surveying on current geo - hazards in the mine of middle of Zhejiang province. The proper prevention measures are suggested through comprehensive evaluation on the construction site in the paper.
The occurrence of geological disaster is confined to certain geological environments and the deteriorated geological environment will lead to new and more serious disaster which will confine the sustainable development of economy and society.
