大型深水斜坡堤开体驳抛填堤心石扩散角度及成型率分析

摘要

针对某大型深水斜坡式防波堤抛填堤心石工程量大、工期紧且抛填质量要求高等特点,大规模采用开体驳抛填的施工工艺,通过认真分析开体驳抛填时水下扩散角度规律,合理布设抛填网格,总结堤心石的成型率,确保了防波堤工程堤心石抛填的进度和质量.%For the large amount of the filling corerocks,tight schedule and the high quality requirement of some large-scale deepwater mound breakwaters,we used the open bottom barges to throw and fill on a large scale.Through analyzing the law of diffusion angle of filling corerocks from the open bottom barges,we laid the reasonable filling grid,summarized the forming rate of corerocks,which can ensure the process and quality of the filling corerocks on the breakwater construction.
