某特殊边界地下室上浮的破坏特征及分析

The failure characteristics and analysis of floating occurred in the a special boundary basement caused by the water-logging

地下空间的使用已变得常见、广泛,而地下室上浮的事故时有发生,水是与地下室上浮密切相关的一个因素。本文通过归纳水的空间分布,总结可能引起地下室上浮的几种情况,同时详细介绍某特殊边界条件的地下室上浮后结构变形与构件裂损特征,分析构件变形和裂损之间的相关性,并通过整体与典型榀分别建模方式分析结构受力特点,分析结果与现场检测结果较为吻合。

The use of underground space has become widely,and the accidents of basement floating happen occasionally. Water is one of the factors associated with the basement floating. First,summarize the spatial distribution of water. Several kinds of situations which may cause the rise of the basement are summarized. At the same time,the structural deformation and crack characteristics of the basement after floating in a special boundary condition are introduced in detail. The relationship between component deformation and crack was analyzed.The structure stress characteristics were analyzed through the overall and typical specimens respectively. The analysis results are in good agreement with the field test results.
