锚杆设计计算中土压力零点的确定

Calculation of Earth Pressure Zero Point in the Design and Calculation of Anchor

随着现代社会的发展及高层建筑的应用，基坑大开挖越来越普遍，基坑边坡的支护方法发展得非常迅速，土层锚杆支护工程是应用较多的一种方法，其计算理论已基本成熟。但在土层锚杆设计计算中，土压力零点的确定方法却没有明确给出，本文经过推导给出简单的土压力零点的确定方法。

With the development of modern society and the application of high - rise building, foundation pit excavations were popular and the foundation pit slope support method had made great progress. The anchor works were employed more successfully in many different slope stabilization methods. But there were no definite method to ascertain the earth pressure zero point. This paper put forward a simply method to ascertain the earth pressure zero point.
