摘 要: | 针对南通地区以砂性土为主的地质条件,通过实例,采用静荷载试验方法探讨了群桩施工后,砂土的挤密效应以及桩间距对预制静压单桩承载力的影响,结果表明:群桩施工后,挤密作用提高了砂性土的强度,增加了桩与土地之间的摩擦力,从而有效提高了单桩的承载力,而且在一定范围内桩间距越小,挤密效应越明显.

Abstract: | By static load test,the test data between constructed single pile and pile-groups in Nantong area characterized by sandy clay are analyzed and compared.The results show that compaction effects produce a significant impact on the bearing capacity of precast static pressure pile.The bearing capacity of pile can be improved by pre-constructing static piles. |
