沿海地区抛填石地质深基坑止水帷幕的应用

Application of Waterproof Curtains on Geological Deep Foundation Pits of Throw-filling Stones in Coastal Regions

针对厦门地区地下存在大量抛填石,同时受潮汐影响的地质特点,探讨某具体工程中各种施工方案的优劣,提出采用冲孔灌注桩+内支撑作为支护结构,使两道止水帷幕互为补充的施工方案。经过工程监测,该方案达到了良好的工程效果。

[ Abstract ] This Paper discusses advantagzes and disadvantagzes ot construction plans ota project and proposes a construction plan which utilizes punched cast-in-situ piles ＋ inner support as the supporting structure to make two layers of waterproof curtains supplement each other targzeting at the geologzic characteristics of Xiamen including largze quantity of throw-filling stones and tide influence. After proiect monitoring, the plan achieved a sound project result.
