| 摘 要： | 随着地铁建设的快速发展,地铁施工中邻近管线的安全评价是一项亟待解决的关键技术问题.在地层移动基本规律认识的基础上,提出了一种经验或半经验的刚性管线纵向应变计算及安全评价方法.该方法可应用于快速评估管线的潜在损害,具体的管线细节一般不予考虑,涉及的参数少,更易于工程应用.该方法尤其适用于没有足够资料或者特殊敏感的条件下,需要采用保守估计的情况.

| Abstract: | With rapid developments of metro construction in China,the safety evaluation of pipelines near tunneling is one of the key technical problems urgent to solve.On the basis of understanding basic laws of ground movements,an empirical or semi-empirical method of longitudinal strain calculation and safety evaluation of rigid pipelines is put forward.Generally it is not necessary to consider the details of pipelines,and only a few parameters are involved,so the method is easier to be used in engineering,and can ... |
