土石坝应力应变分析的目的之一是估算坝坡的抗滑稳定性。比较流行的方法是计算坝体滑动面上的剪应力水平s的平均值,其倒数就是安全因数。这种方法算出的安全因数虽然与极限平衡法算出的安全因数并不完全相同,但比较接近,而且是协调的。但是,《岩土工程学报》1982年第4期发表的“沥青混凝土心墙土石坝的应力应变分析”一文[1],却算出碧流河土石坝上游坝壳中的s值因水库水位上升而增高,这意味着上游坝壳的
One of the purposes of stress and strain analysis of earth-rock dam is to estimate the anti-sliding stability of the dam. The more popular method is to calculate the mean value of the shear stress level s on the sliding surface of the dam, the inverse of which is the safety factor. Although the safety factor calculated by this method is not exactly the same as the safety factor calculated by the limit equilibrium method, it is relatively close and coordinated. However, “Geotechnical Engineering” 1982 the fourth issue of “asphalt concrete hearth embankment dam stress and strain analysis” article [1], but has calculated the Biliu river dam upstream dam shell s value due to reservoir The water level rises and rises, which means the upstream dam shell
