| 摘 要： | 柬埔寨达岱水电站为混凝土面板堆石坝。该工程区地层岩性主要为侏罗系中统的长石石英砂岩、泥质粉砂岩及泥岩,坝区河床表层有橄榄玄武岩覆盖。通过对工程区地层岩性的分析,采取有效的防渗措施及固结灌浆等补强措施后,减少了基础的开挖量,并充分利用河床以下主要为弱透水性泥岩的有利条件降低了工程的防渗标准,从而使工程建设得到优化。

| Abstract: | The Cambodian Tatay Hydroelectric Station belongs to concrete face rockfill dam.The lithology for engineering area is mainly composed of Mid-Jurassic feldspar-quartz sandstone,argillaceous sandstone and mudstone;meanwhile part of dam site river bed surface is covered with olivine basalt.By engineering site strata & lithology analysis,effective anti-seepage and consolidation grouting remedial measures are taken.As a result the foundation excavation volumes are reduced and weak permeability of the mudstone are utilized to rise the engineering anti-seepage standard to further optimize project construction. |
