摘要
通过天津地区几例预应力管桩的静载荷试桩结果 ,分析天津地区预应力管桩单桩竖向极限承载力标准值的估算及与《建筑桩基技术规范》(JGJ 94— 94)和天津市《岩土工程技术规范》(DB 2 9— 2 0— 2 0 0 0 )
On the base of the several static load test results in Tianjin district,analyzing and studying the estimate results of the standard vertical limited bearing capacity of the single prestressed concrete drilled caisson.Furthermore,comparing the results to that of the 〈Technical code for building pile foundations〉.(JGJ 94?94) and Tianjin 〈Technical code for geo?technical engineering〉.(DB 29?20?2000).
