基于现场观测试验,掌握试验段全年大风特征,并对不同类型的阻沙措施与固沙措施的防沙效果进行对比分析。结果表明：百里风区试验段的主导风向为NNW,烟墩风区试验段的主导风向主要为NE、ENE,分别占全年风向的21%和26%；百里风区阻沙措施性价比依次为：金属涂塑网措施>斜插板式挡沙墙>箱式挡沙墙>插板式挡沙墙；烟墩风区阻沙措施性价比依次为：金属涂塑网措施>高立式PE网措施>斜插板式挡沙墙>插板式挡沙墙；固沙措施性价比依次为：芦苇方格>石方格>沙方格；在现场试验研究的基础上,综合考虑工程造价和现场实际情况,建议试验段阻沙措施采用金属涂塑网沙障,固沙措施采用石方格沙障。

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.
