个旧至冷墩二级公路K22+336~+520段预应力锚索桩板墙工程位于个旧市保和乡政府驻地以北沟谷地带。该路段地形横坡陡峻,坡脚局部形成陡壁。工程技术人员对该段工程进行了多次现场勘察,先后提出调整平面线形、采用桥梁跨越等多种比选方案,但均因地形、地质、工程造价高、施工工期长等因素,无法实施。最后在详细研究工程地质状况和认真分析勘察资料的基础上,提出了预应力锚索桩板墙支挡、锚杆框格梁防护等综合处治措施,起到了预想的效果。
Gejiu cold pier two highways K22 + 336 ~ +520 prestressed anchor sheet pile wall project is located in Gejiu City, Baohe township government resident north of the valley. The steep terrain of the section of the terrain, the slope of the foot of the formation of steep walls. Many engineers and technicians conducted on-site surveys on this section of the project, and successively proposed a variety of alternatives such as adjusting plane alignment and adopting bridge spanning. However, they were unable to be implemented due to such factors as topography, geology, high project cost and long construction period. Finally, based on a detailed study of the engineering geological conditions and the careful analysis of survey data, the comprehensive treatment measures of prestressed anchorage pile wall support and bolt grid girder protection are proposed, which have achieved the expected results.
