摘要
结合工程实例,介绍了砂卵石土与泥岩二元地层基桩检测中的静载荷试验、声波透射法和低应变法,并对三种方法试验结果进行分析,以验证桩身完整性与单桩承载力是否满足设计要求.结果表明:三种检测方法各有利弊,在工程中应综合使用.
Abstract
Combined with engineering examples,the static load test,acoustic transmission method and low strain method are introduced in the pile foundation test of binary strata of sandy pebble soil and mudstone,and the test results of the three methods are analyzed to verify whether the integrity of pile body and the bearing capacity of single pile meet the design requirements.The results show that the three methods have their own advantages and disadvantages,and should be comprehensively used in engineering.
