柔性楔形桩复合地基承载特性试验研究
Experimental Study on Bearing Behavior of Composite Foundation with Flexible Tapered Column
摘要
Abstract
For the study of bearing performance of composite foundation with rammed soil-cement piles in silty clay ground, conducted vertical static load contrast experiments under the action of the gravel cushion on three groups of composite foundation with single rammed soil-cement tapered pile of different wedge angle and a group of composite foundation with single rammed soil-cement cylindrical pile, respectively. Analyzed the variation law of pile top settlement, soil around pile settlement and average pile-soil settlement difference with load and the load transferring law of pile. The test results show: Under the same geological condition, the bearing behavior of rammed soil-cement tapered pile is better than that of cylindrical pile, and the tapered pile can better adjust the settlement between pile and soil, in addition the distribution of axial force is relative to the wedge angle of pile, and in rational wedge angle range, the pile sharing load of upper foundation increased with increment of wedge angle; In a certain scope of soil to pile core, the settlement curve appeared the varying tendency of“spoon” type.关键词
