大连星海湾跨海大桥主桥索塔钻孔灌注桩施工

摘要

Taking the cross sea large bridge of Dalian Xinghai Bay as an example,this paper analyzed the engineering geological conditions and characteristics,through the investigation of strata distribution characteristics in sea deepwater karst,discussed the methods to solve the karst geo-logical drilling problems,elaborated the construction technology of main bridge cable bent tower bored pile,pointed out that using this method successfully completed the construction tasks,achieved expected effect.%以大连星海湾跨海大桥为例，分析了工程的地质条件及特点，通过勘察海上深水岩溶地层分布特征，探讨了解决岩溶地质钻孔问题的方法，对主桥索塔钻孔灌注桩的施工技术进行了阐述，指出采用该方法成功地完成了施工任务，达到了预期的效果。
