水泥搅拌桩复合地基承载力的试验确定

DETERMINATION OF BEARING CAPACITY OF DEEP CEMENT MIXING COMPOSITE FOUNDATION BY TEST

能否正确合理地确定水泥搅拌桩复合地基承载力是确保其安全性的一个重要问题。对文献中见到的通过静力载荷试验确定复合地基承载力的方法进行了分析探讨,在此基础上对在工程中如何通过静力载荷试验确定水泥搅拌桩复合地基承载力提出了一些建议:对试桩作单桩和复合地基静力载荷试验;对工程桩只作复合地基静力载荷试验。

It is important to reasonably determine the bearing capacity of deep cement mixing composite foundation for the safety of building. The existing methods for bearing capacity determination of deep cement mixing composite foundation by static load test are discussed in the paper. Some valuable advices are proposed based on the discussion on both static load tests of single pile and composite foundation. The static load tests of both single pile and composite foundation should be made for testing pile,but only static load tests of composite foundation made for engineering piles.
