摘要
通过国内近年来桩底后压浆的工程实例，介绍了泥浆护壁灌注桩后压浆技术的发展。分析了桩底后压浆技术适应的地质条件和有关技术参数，归纳出单桩竖向承载力的估算方法。
By giving some construction cases of pilebottom post pressuregrouting conducted in recent years in China, introduction is made on the development of post pressuregrouting pile. Conditions under the pile and relevant technical references are analyzed, estimating methods of vertical bearing capacity of single pile are concluded. And these can be taken as basis for the preliminary design of a pile distribution plan.
