锤击和静压管桩在某工程中应用效果分析

摘要

通过对锤击和静压管桩工程实例分析，在以砂层为持力层的管桩工程，在建设场地岩土工程条件和桩型相同的条件下，锤击沉桩的管桩承载力明显高于静压沉桩的管桩。在砂性土较厚的管桩工程，采用锤击方法对施工更为有利。在环境条件允许的情况下，选用锤击法施工较为合理。%According to analysis of hammering and static pressure pipe pile in a project ,the bearing capacity of drive pile is higher than static pressure pile-sinking in same geotechnical engineering condition and pile type when sand layer is the bearing layer in pipe pile projects .When the sand layer is thick ,hammering method is favorable to construction . Under conditions permitting ,hammering is more reasonable .
