摘要
考虑管线与土壤之间的相互作用 ,研究了土壤性质改变对埋地管线轴向地震响应的影响 .利用有限元方法对运动方程进行求解 ,对算例运算表明 :剪切模量均匀变化的土壤中埋地管线中点的轴向地震响应与具有相同剪切模量的均质土壤中埋地管线中点的轴向地震响应相同 ;当管线位于两种不同介质中时 。
The effect of varying soil properties on axial seismic response of buried pipelines is studied considering the interaction between the pipe and the soil. The motion equation is resolved in finite element method. The results of actual calculation show that the axial seismic response of pipelines buried in soil with uniformly varying shear modulus is almost the same as that in the soil with the same shear modulus. When a pipeline running through two different media, the peak stresses in the vicinity of the interface increase apparently.
