混凝土等截面刚性心墙在国内第一次应用于澄碧河水库,当时我们曾提出一套公式计算墙身应力[’],这套公式假定地基反力系数κ为常数。本文假定κ为变数,推导出另一套公式,并以实例将两套公式的计算结果进行比较和分析,根据心墙运行情况及十多年来的观测资料,认为后一套公式更符合实际。文中还对其他一些向题提出了讨论性的意见和建议。
For the first time in China, the rigid core wall with concrete cross-section was applied to the Chengbihe Reservoir. At that time, we proposed a set of formulas to calculate the wall stress [’]. The formula assumes that the reaction coefficient κ of the foundation is constant. In this paper, we assume that κ is a variable, derive another set of formulas, and compare and analyze the calculation results of two sets of formulas by examples. According to the operation of the heart wall and the observed data over the past decade, the latter set of formulas is more realistic . The article also made a number of other questions to discuss the comments and suggestions.
