载体桩在太原地区粉土地层中的应用研究

Applied Research of Carrier Piles in the Silty Soil Layer in Taiyuan Area

以太原地区某标准厂房桩基工程为例,研究载体桩在粉土地层的设计应用,结合载荷试验成果对载体桩受力特性进行验证。研究结果表明:以粉土作为持力层的载体桩在工程实践中具有较好的适用性,静载试验与沉降观测表明载体桩承载性能良好,是一种安全经济的基础形式;根据载体桩静载试验结果,表明单桩竖向承载力具有较好的安全储备,能确保工程安全。

Taking the pile foundation project of a standard factory in Taiyuan area as an example,this paper studies the design and application of carrier pile in the silt layer,and verifies the bearing characteristics of carrier pile with the results of load test.The results show that the carrier pile with silt as the supporting layer has good applicability in engineering practice.The static load test and settlement observation show that the carrier pile has good bearing capacity and is a safe and economical foundation form.According to the static load test results of carrier pile,it shows that the vertical bearing capacity of single pile has a good safety reserve,which can ensure the engineering safety.
