关于绞吸挖泥船吹填大粒径卵石挟砂土质的施工生产率及计算方法的探讨

Investigation and Discussion of Construction Productivity of Reclamation of Large-diameter Gravel and Sand Soil by Suction Cutter Dredger and Its Calculation Method

以秦皇岛港煤四期堆场造地工程的实践为基础,在总结施工经验的同时,通过理论分析,提出了津航浚218绞吸挖泥船吹填大粒径卵石挟砂土质时,施工生产率近似求解方法,并与实际生产率进行详细比较。

Based on practice of the reclamation project of the 4th-phase coalstorage yard of Qinhuangdao Port, through summarizing construction experienceand by theoretical analysis, approximate calculation method of constructionproductivity of reclamation of large-diameter gravel and sand soil by suctioncutter dredger is given, and detailed comparison between calculated producti-vity and real productivity is made.
