摘要
通过对南京市内金川河河道挡墙的调查,归纳总结出全程河道挡墙裂缝的发育特征及其分布规律,并运用断裂力学分析计算挡墙裂缝的强度因子,从而为评价河道挡墙裂缝的稳定性提供依据。分析结果表明,挡墙裂缝是影响挡墙稳定性的一个重要因素。
Through the survey of Jinchuan river wall in Nanjing,summarized the whole river retaining wall fracture development characteristic and distribution rules,and use of fracture mechanics analysis and calculation of the intensity factor of cracks in retaining wall,so as to evaluate the river wall cracks provide the basis for stability.Analysis results show that,the wall cracks is an important factor affecting the stability of retaining wall.
