静力触探试验确定粉喷桩复合地基承载力研究

Study on Determination of Bearing Capacity of Dry Jet Mixing Pile Composite Foundation through Static Cone Penetration Test

确定粉喷桩复合地基承载力,一般采用静载荷试验。文内通过对粉喷桩复合地基载荷试验与静力触探试验结果分析后,提出了一种利用静力触探试验确定粉喷桩复合地基承载力的方法。工程应用结果表明,该法可有效地预测粉喷桩复合地基承载力,但还需更多的工程实践进行验证。

It is commonly to determine the bearing capacity of dry jet mixing pile composite foundation with static load test. Through analysis on the results of load test and static cone penetration test for dry jet mixing pile composite foundation, this paper puts forward a method to determine the bearing capacity of dry jet mixing pile composite foundation with static cone penetration test. It is indicated from engineering application that this method can effectively predict the bearing capacity of dry jet mixing pile composite foundation but still requires more engineering practices for verification.
