摘要
针对地基沉降对柔性管道的影响这一课题,利用材料力学中索的受力分析模型对地下柔性管道在地基沉降作用下的情况进行分析,推导出土体处于非极限状态和极限状态两种情况下管道的竖向位移方程,给出了管道拉力、变形的表达式,经过对工程实例进行分析,表明理论计算结果与现场实测值比较吻合。
Aiming at the influence of foundation settlement on flexible duct, the situation of underground flexible duct under foundation settlement effect was analyzed with forces analysis on funiculus of material mechanics. The duct vertical displacement equations under the non-ultimate limit state and ultimate limit state were deduced. The expression of dust pulling force and deformation were given. Through analyzing of engineering exalnp[e, it indicated that theoretical calculation was in good agreement with field measured value.
