地质勘察时，宜根据沉降计算的需要，提供地基土的e～p曲线和持力层的基床系数，并提供桩、土直剪摩擦试验结果。

The engineering geological exploration document should provide the e-p curves of soil , the subgrade coefficient of bearing stratum and the results of direct shear test between the pile and the soil according to the request of settlement calculation .

通过静载试验的验证，以风化岩地基为持力层的CFG桩复合地基在进行桩的设计时，可以采用较稀疏的布桩方式即可满足建筑物的承载力要求。

By static load test verification , more sparse pile can be used to meet the bearing capacity of the building in the CFG pile design , as is based on the weathered rock foundation . 2 .

同时，总结CRG桩在岩溶地区施工工艺，为后续在花岗岩和泥质砂岩持力层中试验成功及工程应用积累经验。

The construction technological process of CRG piles is summarized in karst area . Experiences are accumulated for testing and application of CRG piles to bearing layers in granite and clay sandstone .

花岗岩残积土通常作为摩擦桩的桩端持力层，其工程性状一般接近于粉质砂土（Lumb，1962）。

As a kind of silty sand s ( Lumb , 1962 ), residual granitic soil is normally taken as the end-bearing stratum of friction piles .

较好的建筑物基础持力层均分布于前积层3个旋回顶部的砂层，埋深顶面分别为－20～－25m、－30～－35m、－40～－45m；

The effective bearing strata occur in sand layers on the top of the foreset beds with three cycles . The contours of top surfaces of sand layers are-20 ~ - 25m , - 30 ~ - 35m and - 40 ~ - 45m respectively .
