Taking gravity anchor pit foundation of a long span suspension bridge in carst area as the background, this paper introduced general ways made foundation treatment to pit foundation existed lots of carst and fracture development, and the basic principles and methods of geological exploration, bearing capacity tests and shear tests, in order to verify the capacity after foundation treatment whether or not to meet the design requirements.%以岩溶地区一座大跨径悬索桥的重力式锚碇基坑为背景,介绍了对存在大量溶洞和裂隙发育的基坑进行地基处理的一般方法,以及地质探测、承载力试验和剪切试验的基本原理和方法,以便验证地基处理后的承载力是否满足设计要求。
