摘　　要：本文在文献〔1〕的基础上,研究并获得了滑坡地区管道的变形及应力的解,并以算例分析了管道的极限塌陷长度ι_2max管道中的轴向拉力P随管径D及土壤性质K_(30)的变化关系。Based on the relcrence, this paper rescarcns the deiormauon and stress or the pipeline at lana- slide-prone areas and obtains the solutions as well as analyzes the change relationships of the limit sub- sidence length(1_(2max))and axial direction tensile force(P) with the diameter (D)and soil property(k_(30)) by use of some calculation examples.
