松软土层复合型土钉墙支护稳定性设计与应用

Design and Application of Stability for Retaining and Protection of Complex Soil-nailing Wall in Soft Soil

为了提高土钉墙设计的可靠度 ,在《基坑土钉支护技术规程》CECS96 :97所规定的设计计算和验算项目的基础上 ,结合软弱土层地区的地下水和土的特点 ,利用整体稳定性分析的方法 ,从另外的 4个方面对土钉墙的稳定性进行了验算 ,并在实际工程中进行了应用 ,取得了较好的结果 。

In this paper, to improve the design credibility of soil-nailing wall, the stability of the soil-nailing wall is proved in four ways by using the whole stability analysis method, based on the projects designed and proved by Technical Specification for Retaining and Protection of Building Foundation Excavations CECS96:97 together with the characteristics of the ground water and soil in flabby soil area. A better result is obtained after this method is applied to the engineering. So more theoretical bases are provided by this method for the application of soil-nailing wall in flabby soil area.
