摘    要:本文根据拱坝坝肩稳定计算公式,就温度荷载对拱坝坝肩稳定的影响问题作了初步探讨,结论指出,在一般情况下,温升对拱坝上部坝肩稳定不利,对下部起有利作用,温降则相反;对高拱坝更应注意温降对稳定的不利影响.文中还对拱坝稳定的最不利荷载组合问题以及如何确定拱坝的封拱温度问题作了初步分析.

关 键 词:温度荷载  荷载组合  拱坝坝肩稳定  封拱温度  抗滑稳定安全系数

Effect of Temperature Change on Abutment Stability of Arch Dam

Authors:Liu Defu
Abstract:The variation of ambient temperature can change the stability of arch dams against sliding. The further study has shown that, in a general case, temperature drop has worse effect on sliding stability of abutment of arch dams than temperature rise does. In addition, a method to select the temperature of joint grounting is suggested.
Keywords:temperature load  loading combinations  arch dam abutment stability  temperature joint grounting  safe sliding factor
