摘要
阐述素混凝土桩复合地基与富水软土地基的基本特性,结合四川某工程项目,探讨素混凝土桩复合地基在富水软土地基中的实际运用效果.进行静荷载试验以及低应变检测试验,检测结果显示,单桩竖向抗压极限承载力最大值为800 kPa,最大沉降量为 11.2 mm,复合桩中Ⅰ类桩占检测总桩数的90%,Ⅱ类桩占检测总桩数的 10%,使用合格率达到 100%.
Abstract
This paper expounds the basic characteristics of plain concrete pile composite foundation and water-rich soft soil foundation,and discusses the practical application effect of plain concrete pile composite foundation in water-rich soft soil foundation,based on a project in Sichuan.Static load tests and low strain detection tests were conducted.The test results showed that the maximum vertical compressive bearing capacity of a single pile was 800 kPa,and the maximum settlement was 11.2 mm.Class Ⅰ piles accounted for 90%of the total number of tested piles,while Class Ⅱ piles accounted for 10%of the total number of tested piles.The pass rate reached 100%.
