| 摘 要： | 通过对拟建的镇江至扬州长江公路大桥工程桥基断裂断层岩的矿物组成及显微结构特征、物理力学性质、岩体结构特征的系统研究,提出了断裂的工程分带评价新观点和方法,将桥基断裂在横向上分为4个带,各带的工程对策分别为避开、开挖回填混凝土补强处理、注浆加固和加大桩长。

| Abstract: | Based on systematic study on mineral composition,micro structural charactristic,physical and mechanical property,and rock mass structure of faulted zone under the designed Yangtze River Highway Bridge from Zhenjing to Yangzhou,a new viewpoint and method for engineering zonation and assessment on faulted zone are presented.The faulted zone is divided into four belts.The engineering countermeasures for each belt separately desiged to evade faulted zone,to excavate and fill up with concrete,to consolidate with grouning and to increase the pile length. |
