在镇江地区广泛分布的泥岩是一种软岩,按现行钻探取样方法取得的力学指标结果通常偏低。以该工程为例对泥质软岩嵌岩桩承载力的确定方法进行比较研究,提出以现场天然岩石抗压强度作为入岩控制依据,采用预埋荷载装置法进行大直径端阻力载荷试验结果作为承载力设计依据的建议。经沉降检测,现该主体建筑物已达稳定标准。 Mudstone widely distributed in Zhenjiang area is a kind of soft rock, and the mechanical indexes obtained according to the current drilling sampling method are usually low. Taking the project as an example, the method to determine the bearing capacity of rock-socketed piles with muddy soft rock is comparatively studied. The compressive strength of on-site natural rock is taken as the basis for rock control and the result of large-diameter end-end load test As a basis for design of bearing capacity. After settlement test, now the main building has reached a stable standard.
