粉喷桩复合地基承载力检测方法对比研究

目前，静载荷试验被认为是确定粉喷桩复合地基承栽力的最准确、最有效的方法，但这种方法周期长、费用高。常规勘探方法(包括静力触探、钻探、抽芯检测等)是确定复合地基承栽力的一种快速简便的方法，通过实际工程中两种方法的对比，验证了它的可行性。

The Contrast Study of Test Methods about Bearing Capacity of The Powder Deep Mixing Pile Composite Foundation

At present, static loading test has been thought as the most accurat e and the most effective method to confirm bearing capacity of the powder deep m ixing pile composite foundation. However, the testing method needs longer period ic time and higher expense. Instead of this method, the common exploration metho ds (including static sounding, drilling and sampling test) is a rapid and simple method to confirm foundation capacity. At the same time, its feasibility is con firmed by the contrast of the two methods in practical works.
