Experimental Study on Design Parameters of Retaining Wall for Sandstorm Section of Lanzhou-Urumqi High-speed Railway
摘要
Abstract
The sand roadbed is mainly located in Yandun wind zone and Barry wind zone along double track Lanzhou-Xinjiang railway line. Sand flow is likely to form under strong wind condition. The sand retaining wall plays an important role in the protection of railway. In order to give full play of the sand retaining wall, this paper addresses the causes and regularities of sand flow along the Lanzhou-Urumqi high-speed railway, and the parameters of the sand retaining wall in terms of height and width ratio, porosity and height are compared and tested, finally the optimization design method of sand retaining wall is put forward. The analysis results show that when the sand retaining wall is of a certain height, the protective effect of the sand retaining wall shows a negative correlation with the width. For sand barrier of unified web structure, the porosity of 40% is the best, followed 30% and 50%. The sand retaining wall of 2 m high is recommended followed by 2. 5 m and 1. 5 m.关键词
