城市轨道交通工程周边地下管线监测控制指标
|
摘要
根据城市地下管线的自身特性和变形特点,明确了刚性管线和柔性管线的控制指标。综合分析了地表位移、管线自身位移、应力、应变和转角等地下管线控制指标的相关研究成果。通过北京、上海等地区城市轨道交通工程周边20条管线直接监测结果和153条管线地表间接监测结果的分析,指出工程施工可造成地下管线出现较大的整体沉降,地层较为软弱时管线总沉降量可能远超沉降控制值。地下管线的差异沉降(倾斜率)是控制其安全的重要指标,工程实际应同时控制管线的总体沉降和差异沉降,以合理评价地下管线的安全状态。
The control index is determined for rigid and flexible pipeline according to the characteristics and deformation behavior of city underground pipeline.A comprehensive study was done to the research results on underground pipeline control index,including ground surface displacement,pipeline displacement,stress,strain and bending angles.By analyzing to the 20 direct pipeline monitoring results and 153 surface indirect monitoring results around urban rail transit constructions in Beijing,Shanghai,etc,it is pointed out that engineering constructions can cause significant overall settlement to pipelines,and the settlement may far exceed the control value in soft ground.The differential settlement(slope) of underground pipeline is an important index to control its safety.The overall and differential settlement of underground pipeline should both be controlled in order to give a reasonable evaluation of its safety state.
