摘要
水工隧洞除承受较大的围岩压力外,还要承受较高的外水压力和内水压力,隧洞施工质量要求较高。在隧洞施工期,从节约工程投资的角度出发,业主方常常会提出优化灌浆施工方案的要求。结合工程实例,介绍地质雷达检测技术在优化水工隧洞灌浆方案设计过程中所采取的技术措施及取得的效果。说明地质雷达检测技术应用于优化水工隧洞灌浆方案设计方面是可行的,对水工隧洞的施工质量监测及节约隧洞灌浆成本起到重要作用。
In addition to the surrounding rocks, the hydraulic tunnel ternal water, which requires a higher quality of tunnel construction. withstands the great pressure from external and inDuring the process of tunnel construction, from the aspect of saving project investment, the landlords often ask for optimization of grouting construction scheme. Taking an engineering for example, the author describes the technical measures taken by the geological radar detection technology in optimizing the design of hydraulic tunnel grouting scheme, and its preferable effect obtained. It proves that the technique mentioned above is feasible, which plays an important role in quality monitoring of hydraulic tunnel construction, and saving the cost of tunnel grouting.
