【摘要】 场地岩石力学性质及差异性沉降量大小直接影响建筑物的安全。根据场地区域地质、地震地质和岩石试样测试结果,对场地岩体各项物理力学指标进行了综合统计,并给出了场地各种岩性的地基承载力标准值、设计值、动态地基允许承载力和地基抗震承载力设计值。由此计算出地基沉降量的最大值和最小值,得出地基的差异性沉降量,为核电站设计和建设提供可靠依据。更多还原

【Abstract】 The property of the rock mechanics and magnitude of differential subsidence value of foundation affect safety of buildings directly. On the basis of site regional geology,seismic geology and testing results of rock samples,the physico-mechanical parameters of country rocks are interpreted statistically. The standard values and design values of foundation bearing capacity,dynamic allowed bearing capacity and design values of earthquake-proof bearing capacity for foundation are given. The maximum and minimum values of foundation subsidence are calculated and the differential subsidence values of foundation are obtained. As a result,the reliable basis is provided for design and construction of nuclear power station.更多还原
