STUDY ON INTERACTION OF UNDERGROUND PIPELINE AND SOIL DYNAMICS
-
摘要: 地下管线在维系现代城市功能和区域经济功能中起着举足轻重的作用。相对于理论研究,地下管线抗震性能的试验研究仍较少。以两个相同设计的层状剪切砂箱模拟土体的边界条件,通过基底输入,分别对地下管线在非一致激励下的动力响应规律进行试验研究。试验中改变管径及管线埋深,调整基底输入的频率和振幅,以考察多种因素的变化对管土相互作用的影响。Abstract: Underground pipelines play a decisive role in maintaining the functions of modern cities and regional economies. There are still less researches on the aseismic performance of underground pipelines as compared with theoretic ones. Two layered soil shear sandboxes of same design are used to simulate the boundary conditions of the soil. It is explored the dynamic response law of underground pipelines subjected to non-uniform excitations by means of base input. It is also examined the effect of change in many factors on pipeline-soil interaction by changing the diameter and depth of pipes,adjusting the frequency and amplitude of the base input.
