Erosion control structure is a key accessory engineering of long-distance oil and gas pipelines, and the current methods for calculating the erosion control engineering quantities in the preliminary design stage of oil and gas pipeline can hardly satisfy the demand of budget estimation accuracy. In this paper, an optimized calculation method used for the erosion control engineering quantities in the preliminary design stage of pipeline was proposed with the China-Myanmar Pipeline as an example. Firstly, 9 calculation elements of erosion control engineering quantities of the China-Myanmar Pipeline were investigated by analyzing the factors leading to the deviation of the erosion control engineering quantities in the preliminary design stage and the completion stage of completed oil and gas pipelines, and new formulas for calculating the engineering quantities were set up for erosion control engineering with different materials and structures. Then, the slopes and length coefficients along the China-Myanmar Pipeline were extracted by GIS software(e.g. Global Mapper and ArcGIS), and some parameters in the optimized calculation formula were determined. After the China-Myanmar Pipeline was completed, its erosion control engineering quantities in the preliminary design stage was compared with that in the completion stage. The results show that the calculation accuracy of erosion control engineering quantities in the preliminary design stage is higher.It is proved that this optimized calculation method is feasible and it provides a new idea for the accurate calculation of erosion control engineering quantities in the preliminary design stage.(5 Figures, 5 Tables, 20 References)
