黄土地区铁路蒸发池设计研究

Design and research of railway evaporation pond in loess region

路基走行于黄土平原区常有长段落排水困难的问题。黄土地区铁路建设尤其需要重视排水系统的设计,避免湿陷性黄土地段路基被水浸泡导致的变形、沉降及可能引起的失稳等问题。针对黄土地区铁路建设过程中的此类问题,本文参考公路排水设计在排水困难地段设计了蒸发池,并结合公路排水设计规范对黄土地区铁路蒸发池设计及容量计算进行了研究,提出了一种实用性较强的蒸发池设计方法,并结合银西铁路某段落进行了应用,证明了该设计方法的可行性。

It is often difficult to drain long sections of roadbed in loess plain.The railway construction in loess region should pay special attention to the design of drainage system to avoid the deformation,settlement and instability caused by water soaking of subgrade in collapsible loess region.Aiming at such problems in the process of railway construction in loess area,this paper reference for design of highway drainage design in drainage difficult section of the pool water evaporation,and connecting with the design of highway drainage standard railway in loess areas of evaporation pool design and capacity calculation are studied,this paper proposes a practical design method of evaporation pool,and combined with a certain high speed railway paragraph is applied,The feasibility of the design method is proved.
