通过水泥土强度试验及对埋设4种不同的应变测试载体水泥土试样在无侧限抗压时的应变测定，建立有侧限应力时水泥土应力与应变测试块应变的关系，得到测试水泥土桩桩身应力测试方法。对比试验结果表明：PVC管应变测试块所得数据离差小，对龄期的敏感性小，且7d龄期应变与28d龄期应变随水泥土应力增加而逾接近，可以应用于桩身应力测试。

On the basis of the experiments of cement-soil strength and the strain determination under unconfined compression for the cement-soil samples which laying four different strain test blocks, sets up the relations between the cement-soil stress and the test block strain at a lateral restraint stress, and obtains the stress test method of cement-soil piles. The results of comparative tests show that： the test block of PVC pipe has a minimum deviation and is low sensitive to the cement-soil age, the strain of age 7 days and that of 28 days are closer with the increment of the cement-soil stress, and it can be applied to the stress test of cement-soil piles.
