引洮二期工程八干渠后段地质条件较差,施工过程中经常发生掉块、塌方等地质灾害,特别是八干渠22#隧洞。文章对工程实例进行对比研究,得到了切合实际、经济可行的处理方案。文章针对引洮二期工程八干渠后段22#隧洞新增斜井上游浅埋饱和洞段运用对比分析法讨论洞顶浅埋洞段塌方处理的几种方案,通过分析得到适合该地质条件、投资上经济、技术上可行、效果更佳的施工方案。研究结果表明浅埋饱和土塌方洞段适合运用高压旋喷桩方案处理。文章可为今后类似工程的施工提供有效的参考。
Comparison and Selection of Treatment Scheme of Saturated Shallow Buried Soil of Eight Main Canal of Yintao Ⅱ Project
The geological conditions of the back section of the eighth canal in Yintao Ⅱ Project are poor,and the unforeseen geological conditions such as falling blocks and landslides often occur in the construction process,especially the 22#tunnel of the eighth canal.The article conducts comparative research on engineering instances,and has obtained a processing plan that is practical and economical.The article targets several solutions for the land-slide processing of the lavext section of the upstream shallow saturated hole in the 22#tunnel of the eighth canal in the Yintao Ⅱ Project.Through analysis,construction plans that are suitable for the geological conditions,investment economy,technical feasibility,and better effects are obtained.The results of the study show that the shallow buried saturated soil cave section is suitable for treatment with a high-pressure rotor spray pile scheme.The article also provides an effective reference for the construction of similar projects in the future.
