Prevention Technology Of Earthquake Disaster On Highway Slop

Our country located between two major seismic zone--the circum-Pacific seismic beltand the Eurasian seismic belt, Earthquake occurs frequently, Geological disasters often causecollapse, landslides, debris flow, the Rolling Stones, cracking. Serious impact on the normaloperation of the earthquake area highways, huge economic lossesFor the destruction of the wenchuan earthquake highway slope situation, the paperrelevant information at home and abroad on the basis of research and engineering surveys,carried out the following tasks:（1）Through the history of earthquakes and seismic conditions of environmentalresearch, analyzes the main features of the destruction caused by the earthquake and thehighway west slope seismic safety conditions.（2）Through the surrounding areas of slope failure caused by the earthquake situationand characteristics of the survey on the damage caused by aftershocks characteristic slope.（3）On the highway slope stability and geological conditions of the quake zone afterthe earthquake were investigated, Geomorphic units including stratum structure, lithologicfeatures, weathering degree of rock mass, engineering geological petrofabric, characteristicsof geological structure,slop fracture, joint, fault,and slop rock fragmentationdegrees.statistical analysis of the relationship between the slope failure caused by earthquakesand seismic parameters.（4）On the basis of engineering surveys and data analysis,study the major factorsaffecting road slope stability, and highway slope failure mechanism of the earthquake.（5）Investigate the highway slope seismic design technical and standards in the westernregion with different seismic intensity and terrain, studied the seismic design parameters ofthe west slope of the selection method,proposed the disaster prevention and mitigationmeasures of highway slope.（6）Using pseudo-static method and the proposed method to analyze the seismicstability of high slope typical road conditions, the proposed method in which to considerchanges in seismic force declination. According to the stability of the evaluation results,based on highway slope seismic preventive measures, we put forward concrete anti-seismic and reinforcement measures of typical highway slope.
