| 摘 要： | SMW工法具有防渗性好、构造简单、施工速度快、工程造价低等优点,广泛应用于大型隧道工程、城市地下空间开发、高层建筑深基坑开挖支护工程等。以某城市深基坑工程的SMW工法围护结构为研究对象,在考虑水泥土与型钢的相互作用下,建立有限元数值模型,分析开挖过程中墙体位移和土体变形特点。结果表明:开挖深度对墙体侧向位移有显著影响;随着坡面荷载的增加,基坑内外水平方向和竖直方向沉降量均有所增大。

| Abstract: | SMW construction method is widely used in large tunnel engineering,urban underground space development,and deep excavation of high-rise building project for its efficient anti-seepage,simple and fast constructed,and low cost.In the paper,for the study of a city SMW deep excavation of the building,a finite element numerical model was established by taking into account the interaction between cement and steel.The characteristics of wall displacement and soil deformation were analyzed during the excavation.The results show that the influence of excavation depth to the lateral displacement of the wall is significant;with the increment of slope loading,the amplitude of foundation settlement in both horizontal and vertical directions becomes larger. |
