Engineering Geology and Seismology Conditions Evalution for Long-line Engineering Site——Taking the Yongdeng-Gulang Freeway as An Example

WANG Ai-guo1,2,YANG Bin2,ZHOU Jun-xi2(1.Lanzhou Base of Institute of Earthquake Prediction,CEA,Lanzhou 730000,China;2.Earthquake Administration of Gansu Province,Lanzhou,730000 China)  
Taking the Yongdeng-Gulang Freeway as an example,through the field geology investigation,physical prospecting and borehole surveying,the detailed study and classification are implemented on topographical feature,hydrological geology conditions,lithologic characters of stratum,tectonic geology conditions and earthquake risk along the freeway.Based on above works,the engineering geology and engineering seismology conditions are evaluated on different segment of the freeway.The results show that in different segments of the freeway there are different geology problems and particular engineering earthquake conditions,so in design and construction it is necessary to take different corresponding measures for the problems and characteristics in each segment.This engineering project could be taken as an example for explicating the content and way of the work on engineering geology and seismology conditions evaluation in long-line engineering site.
