Title: Determination of stress field in buried thin pipelines resulting from ground subsidence due to longwall mining
Abstract: When a pipeline is laid across a subsidence-prone area as a result of underground longwall mining, it is not always necessary to take measures to protect the full length of the pipe. In this paper, some guidelines are proposed for partial or full protection in order to prevent possible damage to the pipeline. The techniques of determining the magnitudes and locations of the maximum tensile and compressive stresses on the pipeline are developed. They are based on the assumptions that the pipelines are thin and that the ground subsidence can be predicted by the probability function integration method fairly well. Also, two computer programs are developed to assist in the determination of the optimal control parameters of a subsidence profile and to evaluate the stresses on the pipeline.
