马骝洲水道过江隧道极限冲刷遭遇分析

摘要

Modaomen River is the main spillway in Xi River. Floods and tidal power interact with each other. Flood season runoff effect is very strong. Maliuzhou River is an important branch of Modaomen. Years of measured topographic data show that Maliuzhou River has been in a state of scour. Analysis of flood and tide encounter for tunnel Limit erosion is one of the important preparations in limit erosion calculation. In this paper, the author uses series of measured data within years of the Makou station, Maliuzhou tide level station and Neigang tide level station to conduct encounter analysis of scouring calculation, and thus provides the boundary conditions for the limiting scour calculation.%磨刀门水道是西江的主要泄洪通道,洪潮动力交汇,汛期径流作用较强,而马骝洲水道是磨刀门水道重要分汊,多年实测地形资料表明马骝洲水道一直处于冲刷状态.极限冲刷洪潮遭遇分析是极限冲刷计算的重要准备工作.利用马口、马骝洲潮位站、内港潮位站多年实测系列资料,作冲刷计算遭遇分析,为极限冲刷计算提供边界条件.
