摘要
Abstract
According to the special flow characteristics of flood storage and detention area and the drainage requirements of urban roads,a pipe soil water solid coupling numerical model is established,and the effects of incoming water level,velocity and direction on culvert structure and subgrade stability are considered.The results show that the first inflow mainly affects the stability of the intake,and the increase of unit width flow in front of the culvert leads to the maximum stress concentration and deformation;The effect of incoming water level and ve-locity on the improvement of pipe culvert discharge capacity is limited,and the backwater in front of the cul-vert and subgrade scouring are easy to be caused when the hydraulic calculation is unreasonable;Oblique in-coming water will reduce the drainage efficiency of pipe culverts and aggravate bank scouring.关键词
