摘要

在模拟白鹤滩拱坝横缝、坝基交接面和地基可能滑块的基础上

对坝与地基系统进行有限元网格剖分

计入地震动能量向无限远域地基逸散的地基"辐射阻尼"效应

通过超设计地震作用的超载计算和在设计地震作用下降低地基滑块结构面抗剪强度的降强计算

综合分析坝与地基残余位移、缝面开合情况以及坝基交接面开裂范围及其对灌浆帷幕的影响等

获得白鹤滩拱坝超设计地震的超载安全系数约为2.0

设计地震作用下强度储备安全系数约为2.0

白鹤滩拱坝满足设计和校核地震的抗震稳定要求且具一定的超载能力的结论。

Abstract

The Baihetan Arch Dam foundation system finite element model was established

in which contraction joints

dam foundation interface and foundation potential sliding blocks were simulated

and the viscoelastic artificial boundary was adopted to absorb out-propagating wave energy.A series of calculations were completed by the overloading and shear strength reduction method.Based on comprehensively analyzing dam foundation system residual displacements

dam-foundation interface opening range and its influence on grout curtain as well as the relationship between the residual displacements and overloading factor or strength reduction factor

it can be concluded that Baihetan Arch Dam′s overloading safety factor is approximately 2.0（compared with design earthquake）and the strength reserve coefficient is approximately 2.0.The conclusion shows that Baihetan Arch Dam meets the demand for design and checking earthquake and has some overloading ability.
