摘　　要：嵌岩灌注桩是当前较为常用的基础形式,但在软质岩层中嵌岩桩的承载性状的理论分析、试验和测试研究还不能适应工程的需要。通过对某工程在泥质粉砂岩层上所做的单桩静载试验,测试了桩周侧阻力及端承力,对嵌岩灌注桩在软岩中的承载性状进行分析。Rocksocket castinsitu piles is a commonly used style of foundation, but theoretical analysis, experiment and test research on bearing capacity behavior of rocksocket piles in soft rock cannot yet meet the requirement of engineering. This paper offers a project's static loading test of single pile in argillaceous and silt laminate, in which the skin friction and point bearing capacity are measured and the bearing capacity behavior of rocksocket castinsitu piles in soft rock is analyzed.
