限排模式下地铁共建管廊综合井渗流规律研究
Study of seepage laws of comprehensive wells in metro co-construction pipe gallery under limited drainage mode
摘要
Abstract
Taking the co-construction pipe gallery of Shenzhen Metro Line 14 as the engineering background,a self-designed test setup is used to simulate and study seepage laws of comprehensive wells under different permeability coefficients of permeable blind pipes.At the same time,a seepage model of comprehensive wells is established using COMSOL software to study permeability coefficients of permeable blind pipes.By comparing the results of the model tests and numerical simulations,the accuracy of the numerical model is verified.Subsequently,seepage laws of comprehensive wells under different diameters of permeable blind pipes are studied.The results show that the pore water pressure corresponding to different permeability coefficients of permeable blind pipes decreases with time,and the decrease rate is first fast and then slow.Within the same time period,as permeability coefficient of permeable blind pipes decreases,the change in pore water pressure ranges from 1.87 kPa to 1.96 kPa.Additionally,the pore water pressure increases as the permeability coefficient of permeable blind pipes decreases,with an increase ranging from 0.01 kPa to 1.27 kPa.When the permeability coefficient of permeable blind pipes is greater than 1.192 m/s,the pore water pressure outside the side wall does not decrease,while when the permeability coefficient of permeable blind pipes is less than or equal to 1.192 m/s,the decrease amplitude of the pore water pressure outside the side wall is 0.001-0.012 MPa.As the diameter of permeable blind pipes increases,the decrease rate of the pore water pressure first increases and then slows down,and the maximum change in pore water pressure occurs near the side wall of the drainage system.In summary,it is recommended that the diameter of permeable blind pipes ranges from 0.10 m to 0.16 m.关键词
