概述 土的破坏主要是由于剪切 路堤 引起的,剪切破坏是土体 破坏的重要特点 (a) 工程时间中与土的抗剪强 度有关的工程主要有以下 3类 (1)土质土坝的稳定 挡土墙 (2)土压力 (3)地基的承载力问题 基础
概 述 ▪ 土的破坏主要是由于剪切 引起的，剪切破坏是土体 破坏的重要特点 ▪ 工程时间中与土的抗剪强 度有关的工程主要有以下 3类 （1）土质土坝的稳定 （2）土压力 （3）地基的承载力问题
工程实例一土坡稳定 This photo shows failure of a tailings dam retaining gypsum tailings in Florida.It can be seen that the wet gypsum tailings flowed like a viscous liquid when the dam failed IG. 3 FAILURE OF A GYPSUM TAIL INGS POND Duncan
工程实例－土坡稳定 ▪ This photo shows a failure of a tailings dam retaining gypsum tailings in Florida. It can be seen that the wet gypsum tailings flowed like a viscous liquid when the dam failed
工程实例一土坡稳定 This tailings dam in South africa retained tailings from a platinum mine. Note the very flat slope formed by the tailings 2的 as they came to rest, indicating their very low shear strength

工程实例一土坡稳定 The slide extended for about 1100 feet along the embankment. At the north end. near the inlet outlet structure visible in this photo, the scarp at the top of the slide was about 30 feet high At the bottom of the slope the toe of the slide moved horizontally about 30 feet out into the reservoir
