本文介绍了长诏水库混凝土砌石坝的稳定性模型试验的情况.施工过程中发现长诏坝基下半风化岩体中埋藏有多条夹泥层,其摩擦系数较低.设计选用在坝趾后建齿墙,利用齿后岩石共同保证挡水坝的稳定.总共进行了两种齿墙十一种情况的试验研究.本文还叙述了长诏坝稳定试验中的一些试验技术问题,包括P(作用于上游坝面的水压力)—δ(水平位移)曲线的形态,夹层材料的模拟和层面中初应力的影响等问题.
In this paper, the stability model test of Changzhao Reservoir Concrete Masonry Dam is introduced. During the construction process, it is found that there are many mud layers buried in the lower semi-weathered rock mass of Changzhang Dam with lower friction coefficient. After the construction of the tooth wall, the use of rock after the rock together to ensure the stability of retaining dam.There are a total of two kinds of gear wall eleven kinds of experimental research.This paper also describes the Changzhang dam stability test of some experimental techniques, including P ( The water pressure acting on the upstream dam surface) -δ (horizontal displacement) curve, the simulation of interlayer material and the influence of initial stress in the surface.
