象山隧道岩溶段注浆技术优化研究

为了快速通过象山隧道岩溶段，贯通全隧，通过引进专业化注浆队伍，优化注浆技术，提高注浆效果，保证安全快速开挖。对原注浆方案，注浆工艺、注浆效果评定标准优化和研究，提出象山隧道岩溶段注浆施工技术，即保证了注浆效果、加快了施工进度，又节约了施工成本。通过实践应用证实优化后的施工方法具有明显的经济效益和社会效益，值得在类似工程中借鉴和推广。

Optimization of Grouting Technologies for Karst Sections: Case Study on Xiangshan Tunnel

 Professional grouting teams are introduced and grouting technologies are optimized to improve the grouting efficiency and to guarantee the safe and rapid construction so as to pass through the karst sections of Xiangshan tunnel successfully.  The original grouting plans, grouting technologies and grouting effect assessment standards are optimized and studied and grouting technologies for the karst sections of Xiangshan tunnel are proposed. In the end, the grouting effect is guaranteed and the construction progress is accelerated. The practice proves that the technologies optimized have significant economic and social benefits and are worth to be popularized in similar works.
