刚性桩复合地基设计分析

Analysis and Discussion on Design of Rigid Pile Composite Foundation

刚性桩复合地基设计应根据不同情况确定面积置换率计算方法,并依据实际使用地基承载力特征值计算桩身强度,选择压缩性相对较低的土层作为桩端持力层,采用合理的褥垫层厚度,充分利用桩及桩间土的承载力,做到刚性桩复合地基设计的安全、经济。

The calculation method of area replacement rate should be determined according to different situations in the design of rigid pile composite foundation, and the pile strength should be calculated according to the actual value of the bearing capacity of foundation.The soil with relatively low compressibility should be selected as the bearing layer of pile end.Reasonable cushion thickness, make full use of the bearing capacity of soil between piles and piles, so that the design of rigid pile composite foundation is safe and economical.
