中文摘要:雅砻江锦屏一级水电站左岸抗力体发育有f2、f5、f8、f42-9断层、煌斑岩脉及深部裂缝等软弱带，需采用相应的工程方法对这些部位进行加固处理。化学复合灌浆是在水泥灌浆基础上发展起来的一种基础处理方法，从化学浆材的选择、灌浆参数的确定、灌浆施工工艺等方面介绍了化学复合灌浆在左岸抗力体煌斑岩脉加固处理中的试验情况。根据试验结果对试验区煌斑岩脉的可灌性进行了分析，并通过岩心观察、岩体透水率、岩体声波和孔内变形模量等资料的对比分析对灌浆效果进行了检测评价，评价表明化学复合灌浆对煌斑岩脉的加固处理效果明显。最后根据本次灌浆的试验结果提出了建议。

Analysis on Chemical Compound Grouting Tests of Jingping Ⅰ Hydropower Station Lamprophyre Dike
Abstract:The left resistance block of Jinping I hydropower station on Yalong River was built on f2、f5、f8、f42-9 faults and the weak belt with lamprophyre vein and deep fractures, reinforcement treatment was necessary. Chemical compound grouting was developed based on cement grouting, the test was introduced in selection of chemical grouting material, determination of grouting parameters and grouting construction technology. Based on the test result, analysis was made on grouting feasibility in lamprophyre vein and testing evaluation was made on grouting effect by the comparative analysis on core, permeability of surrounding rocks, rock acoustic wave and deformation modulus in borehole, it showed that chemical compound grouting has obvious effect on reinforcement treatment in lamprophyre vein. The paper also gives the construction suggestion according to the grouting test.
