山区城市高边坡下深基坑工程实例

Example of Deep foundation Pit Engineering below Hlgh Slope in Mountainous City

本文以福建三明市某高层建筑的基坑支护工程实例，说明山区城市建有房屋的高边坡下的深基坑支护设计的若干特点，重点介绍大桩距、大刚度人工招孔围护桩的设计、边坡与坑侧变形的统一观测和简明划分、信息化施工原理的应用等。

Based on the examlpe of foundation pit bracing of a high-rise building in Sanming city,this article attempts to expound the characteristics of deep foundation pit bracing design. The man-dig bored piles with large pile space and great stiffness,concise division of consistent obser vation of the deformation of slope and the pit wall,and the application of the principle of informa-tionalized construction,etc. are emphasised.
