Through the model test in soil slot, the process of deformation and destruction of soft pipeline caused by subsoil settlement is simulated and observed in lab. Based on the experimental data, the curve as the internal force of pipeline is first drawn out and discussed, in turn the characteristic of stress distribution and destruction rule of pipeline are analyzed and summarized, which may be referred for designer to take appropriate measures. The experimental results show that the internal force and deflection of the pipeline increase with the depth and width of the hole below the pipeline. When the hole depth (h)/ pipeline diameter (D) =2.5, internal force and deflection changes only associate with the width of the hole (b). And when b/D =6, the pipeline can not work normally and even be destroyed. The experimental conclusion can provide the basis for the security of underground pipeline.
