一、概述 众所周知,坝工问题的影响因素很多,往往使分析变得相当复杂而难以下手。由于模型试验技术的发展,许多设计中感到棘手的问题可借助于模型试验得到了解决。虽然试验是近似的,但它给出了工程上的解决方法。如图1所示,某高120m的重力坝溢流坝段,在研究其深层抗滑稳定问题时,作为由坝体、岩体、断层、软弱夹泥层等组成的所谓复合结构来分析,问题就十分复杂,许多因素彼此错综地互相影响着,使我们一时难以弄清楚各个影响因素之间内在的联系。因此,不得不采用试验设计的方法,以寻求解决问题的新途径。
First, an overview As we all know, dam workers influence many factors, often make the analysis becomes very complicated and difficult to start. Due to the development of model testing techniques, many of the problems that are troublesome in design can be solved by means of model tests. Although the experiment is approximate, it gives an engineering solution. As shown in Fig. 1, when a 120m high gravity dam overflow spillway segment is studied as a so-called composite structure composed of a dam body, a rock mass, a fault, a weak clayey soil layer and so on, The problems are so complex that many factors interact with each other intricately and make it hard for us to find out the inherent linkages between the various influential factors. Therefore, we have to adopt the experimental design method to find new ways to solve the problem.
