The excavation shape of the pipeline trench changes constantly with the change of terrain, topography and geological conditions along long-distance oil/gas pipelines, so it is difficult to accurately calculate the earth and rock excavation volume of the pipeline trench. In this paper, the geometric model of pipeline trench was established according to the technical requirements of oil/gas pipeline trench excavation. Then, the complex geometric model of oil/gas pipeline trench was divided into two types, i.e., linear volume unit and circular curve volume unit. The accurate volume calculation formula for both volume units are solved by means of the integral method. The calculation formula of circular curve volume unit is more complicated, and it is checked by fitting the arc with multiple line segments. The result shows that the calculation formula of circular volume unit is reasonable and can be used to calculate the earth and rock excavation volume of oil/gas pipeline trench.(4 Figures, 2 Tables, 20 References)
