地下连续墙垂直承载力试验研究

近年来，把地下连续墙作为承重结构的工程实例越来越多，为了给方后的设计和施工提供合理的依据，我们在国内首次进行了单片的连续墙的垂直静荷载现场试验，对地下墙的荷载传递机理及垂直承载力进行了研究，分析了墙端阻力和侧壁摩阻力随位移发展而发挥的特性及它们之间的相互影响关系，提出了侧壁摩阻力的计算模型及地下连续墙垂直承载力的设计方法，可供工程界参考应用。

Vertical Bearing Test of the Diaphragm Wall

In recent years, more and more projects are employing diaphragm walls as bearing structures. To provide rational parameters for future designs and construction an in-situ vertical static load test of a single section of the diaphragm wall was first made in our country. This paper presents in detail load transfer mechanism and vertical bearing capacity of the diaphragm wall, and analyses the characteristics of the mobilization of point resistance and skin friction with the development of displacement and the mutual influence between them. In this paper, the calculation model for skin friction and the design method for vertical bearing capacity of the diaphragm wall are also provided for engineers.
