摘要
博格多山山前漫流地区水流紊乱,串流情况严重,水文情况十分复杂,桥涵布置和设计流量的确定不仅要重视理论计算,更重要的是要重视外业调勘。文章通过鄯善至沙尔湖铁路专用线水文勘察,漫流地区的地形、地貌,水文计算,选取合理的水文计算参数推算桥涵工点的设计流量,合理的确定了线路高程、路堤防护高度、桥涵位置、桥涵孔径的大小、导流建筑物的布设。
In the overflow area in front of Bogeduo Mountain, the water flow is disordered, cross flow is serious and hydrologic condition is very complicated. Therefore, determination of bridge and culvert layout and designed flow pays attention to not only theoretical calculation, but also field investigation. In this paper, according to hydrologic survey, landform and topography in the overflow area and hydrologic calculation of Shanshan-Sha＇erhu Special Railway, the rea- sonable hydrologic calculation parameter is selected to calculate the designed flow at bridge and culvert construction site and determine the elevation of the route, protection height of the embankment, location of bridge and culvert, size of bridge and culvert span and layout of diversion structure, which will provide some references for other similar railway engineering.
