摘　　要：广西大藤峡南木江副坝工程地质较为复杂,存在破碎带。为保证上部混凝土建筑物稳定及安全,提出了河床坝段岩体有盖重固结灌浆方案。在坝下0+005.00~坝下0+009.00开展生产性试验,灌浆试验后采用压水试验及抽芯检测。试验结果表明,该有盖重固结灌浆方案对南木江副坝工程复杂地质条件的处理具有可行性,可用于下一步有盖重固结灌浆施工。Guangxi Datengxia Nanmujiang Secondary Dam has complicated engineering geological conditions with fracture zones. A scheme of rock covered heavy consolidation grouting in the river bed dam section is put forward in order to ensure the stability and safety of the upper concrete building. The production test is carried out from 0+005.00 below the dam to 0+009.00 below the dam. The water pressure test and core pulling test are adopted after the grouting test. The test results show that the proposed scheme of covered heavy consolidation grouting is feasible to deal with the complex geological conditions of Nanmujiang Secondary Dam Project, and it can be used in the next stage of the covered consolidation grouting construction.
