【摘要】 通过山东省某立交桥工程场地地震构造环境、地震活动特征和场地条件勘探,评价了工程场地的稳定性。利用地震危险性概率分析方法获得了场地50年超越概率10%、5%和2%,100年超越概率5%和2%的基岩地震动参数。采用一维剪切波理论进行了场地土层地震动反应分析,确定了工程场地抗震设计参数。本项研究成果为山东省某立交桥工程选址和抗震设计提供了科学依据。更多还原

【Abstract】 In this paper, Based on the seismotectonic environment, earthquake activity characteristics and site conditions of exploration on engineering site of the overpass, in Shandong province, we have evaluated to the site stability. When the transcendental probability is 10%,5%,2% in 50 years and 5%,2% in 100 years respectively,the ground motion parameters of the site on Bedrock is obtained with seismic hazard analysis.Based on one dimensional shear wave theory,the seismic response of the site is analyzed,and the design aseismic parameters are determined.The results have provide scientific basis for the Project location and aseismatic design of the site for the the overpass, in Shandong province.更多还原
