土层锚杆(简称土锚)技术已相当普遍地应用于边坡稳定、挡墙支护、地下结构抗浮、高耸结构抗倾覆等工程项目。但还没有在饱和含水软地层中应用的先例。沿海城市的建设需要在建筑群中开挖深基坑,基坑边坡支护要求研究土锚技术。本文介绍在上海饱和软地层中应用土锚技术的一次试验研究。 Soil anchor bolt (referred to as soil anchor) technology has been quite commonly used in slope stability, retaining wall support, underground structure anti-floating, high-rise structure anti-overturn and other engineering projects. However, there is no precedent for application in saturated soft-water formations. The construction of coastal cities requires the excavation of deep foundation pits in the buildings. The foundation pit support requires the research of the soil anchor technology. This paper presents a pilot study on the application of soil anchor technology in saturated soft formations in Shanghai.
