【摘要】 提出了一种新型桥梁竖向泄水管用以解决桥梁泄水管处渗漏的病害问题。在多孔介质非饱和渗流理论的基础上以有限元软件ABAQUS对新型、普通泄水管周围混凝土进行模拟得出其渗流场分布规律,结果证明新型泄水管能够有效防止桥梁竖向渗流。更多还原

【Abstract】 A new type of bridge vertical drain pipe is proposed to solve the leakage problem of bridge drain pipe. On the basis of unsaturated seepage theory of porous media,ABAQUS is used to simulate the seepage field distribution of concrete around the new and ordinary drainage pipes. The results show that the new drainage pipes can effectively prevent the vertical seepage of bridges.更多还原
