Erqi Yangtze River Bridge at Wuhan is 7th bridge across the Yangtze River. It is 3.2km from 2th Yangtze River Bridge at wuhan in upstream,and 6.8km from Tianxingzhou Yangtze River Bridge in downstream. The bridge walks along the dawn track of Jingguang Railway, through the liberation boulevard at hankou and Jiangan bay railway organization, and cross Yangtze River over pumping house Luojia port at Wuchang, along Luojia port drainage channel to the Peace avenue. The main structure is composite beam cable-stayed bridge with three towers, and its 1732m (90+160+616+616+160+90) long.Harf of the foundation of the 5th pier is situated at the side slope. So its significant to protect the slope before foundation construction. The protective measures of the project is combined on Retaining piles and anchor age piles. The Protection system is designed to a very strong rigidity through prestressing force between two rows of bored pile. At present, the foundation construction has been completed, and the construction of the pylon is on going. The safety problems such as collapse and cracking didnt happen ever. The fact proves that the design is feasible.【关键词】长江 边坡 防护 设计 施工【英文关键词】YANGTZE RIVER SLOPE RETAINING DESIGN CONSTRUCTION【目录】武汉二七长江大桥边坡防护设计与施工摘要6-7Abstract7第1章 绪论10-201.1 国内外研究现状101.2 问题的提出10-111.3 本研究的主要工程简介11-201.3.1 工程概况11-191.3.2 边坡地质191.3.3 边滩防护设计介绍19-20第2章 二七桥520-292.1 设计基本思路20-212.1.1 极限状态设计原则202.1.2 荷载效应原则20-212.1.3 设计总体方案212.2 防护桩计算21-242.2.1 计算桩的入土深度21-242.2.2 防护桩设计242.3 锚桩设计24-262.3.1 计算桩的锚固深度24-262.3.2 桩身强度计算262.4 边坡防护整体抗滑验算26-272.5 分配梁计算27-29第3章 二七桥529-573.1 总体规划29-323.1.1 施工概况29-313.1.2 施工准备31-323.2 防护体系施工32-483.2.1 防护桩体施工32-443.2.2 防护桩分配梁施工443.2.3 防护桩预应力施工44-483.3 管理体系48-573.3.1 质量保证体系48-513.3.2 安全生产保证体系51-533.3.3 文明施工环保保证体系53-57结论57-58致谢58-59参考文献59-61个人简历610万U豆体验卡卡号：50D890668267e3349e33密码：686d03401eefba96faba奖品名称：500万U豆体验卡卡号：50De7a00c543af387fc0密码：b26488ce65abc1787202奖品名称：500万U豆体验卡卡号：50Dbac63885c802fd52e密码：3d1c344384327b85efff奖品名称：500万U豆体验卡卡号：50Dd97f0765bdf6998a3密码：48db1c14e42a2b321fac奖品名称：500万U豆体验卡卡号：50D61215eb41ae3cc919密码：25bffae5346e7b7d2548奖品名称：100万U豆体验卡卡号：10D1cab621456ab278ab密码：709f65f32865af2559c2奖品名称：100万U豆体验卡卡号：10D8f1d6a4b953f3474e密码：6e2e4017cce30dc7e055奖品名称：100万U豆体验卡卡号：10Dd1fc6d6dd529b6892密码：a5dbdd8338f91d2c0701奖品名称：100万U豆体验卡卡号：10D08377b71d4374262b密码：1d7a7c21ebd99b798a54命运如同手中的掌纹，无论多曲折，终掌握在自己手中=
