摘　　要：结合青岛某工程3根嵌岩桩静载荷试验,研究了强风化泥质粉砂岩上的嵌岩打入桩承载力和沉降性状。试验结果表明:在竖向荷载作用下,3根试桩均达到了设计要求的单桩极限承载力,桩顶总沉降均小于40mm。Based on the static load test of 3 rock-socketed piles of a project in Qingdao, the bearing capacity and settlement behavior of the driven pile on strongly weathered silty sandstone were studied. The test results show that under the vertical load, the 3 piles reached the ultimate bearing capacity of the design requirements, and total settlement of the pile top was less than 40mm.
