1、锁口钢管桩在桥梁基础工程施工中的应用研究摘要本文阐述了桥梁基础施工中围堰、基坑围护的常用施工方法及其实施手段，介绍了锁口钢管桩在该领域的应用现状、发展动态以及广阔的应用前景。结合宁波市芝兰大桥水中墩锁口钢管桩围堰设计与施工实践，通过结构计算、结果分析，发现了等值梁理论在不对称侧压下的不适用性，提出了等值梁法理论在特殊工程条件下结构计算模型的修正方法及施工对策，不仅完善了等值梁理论的工程适用范围，而且克服了施工过程中河床管涌、锁口漏水、支撑平面失稳等困难；等值梁计算理论在宁波市芝兰大桥中的发展完善和成

2、功实践，为同类工程的设计计算和工程施工具有参考价值。通过对国p龟#l-桥梁基础施工领域各种方法的比较，得出了基于环保、安全、经济、文明、快速的全新施工理念和革命性的施工方法是当今桥梁基础施工发展方向的结论；对广大工程技术人员更新观念，发展绿色、环保的施工方法与实施手段具有现实指导意义。关键词：桥梁基础：锁口钢管桩；围护结构；等值梁计算方法；施工对策。同济大学硕士学位论文Researchontheapplicationoforifice--lockedsteel--pipepiletobridgefo
