Benefit Evaluation of Sand Prevention Measures in Strong Wind Area along Second Lanzhou-Xinjiang Railway Line
摘要
Abstract
With field observation and test, annual wind characteristics in the test section are mastered, and comparative analysis is conducted of sand control effect by means of sand preventing and fixing sand measures. The results showed that the dominant wind direction in 100 km Wind Area test section is NNW, the dominant wind direction in Yandun Wind Area test section is mainly NE, ENE, having accounted for 21% and 26% of annual wind direction respectively. The performance-price ratio of prevention measures in 100 km Wind Area is as the following: metal coated wire mesh sand barrier> oblique inserting sand retaining wall plate >sand box retaining wall>inserted plate retaining wall of sand. The performance-price ratio of fixing sand measures in Yandun Wind Area is as the following: metal coated wire mesh sand barrier>the high vertical PE net sand barrier > oblique inserted sand retaining wall plate> plate inserted retaining wall of sand. The performance-price ratio of fixing-sand barrier is as the following;reed square >stone square>sand square. On the basis of comprehensive consideration of the project cost and the actual field situation, the metal coated wire mesh sand barrier is recommended for preventing sand and he metal coated wire mesh sand barrier is recommended for fixing sand.关键词
