摘要；分析长江城陵叽到螺山河段行洪能力的变化和三峡水库运行后该河段面临的防洪形势，指出降低城陵叽河段水位的有效措施之一是恢复河道原有的泄洪能力，实施牌洲裁弯，清淤疏浚和削叽扩卡等为主的工程措施。并以典型洪水为例对牌洲裁弯前后相关河段的水位，水面线及水位流量关系的对比分析，论证了牌洲裁弯对降低上游水位的明显作用和该工程的必要性。关键词；三峡工程，长江 成汉河段 泄洪能力变化 河道整治

Abstract; Analysis of the Yangtze River city of hills grumble to Luoshan ability to change and flood the Three Gorges reservoir operation after the river facing the flood situation, pointed out that the river water level to reduce the city hills grumble is one of effective measures to restore the original flood discharge capacity of river channels the implementation of paizhou cut-off, dredging and expansion cards cut grumble mainly engineering measures. And to a typical example of paizhou floods before and after the relevant cut-off river water level, water lines and comparative analysis of stage-discharge relationship was demonstrated paizhou bend to reduce the apparent role of the upstream water level and the need for the project. Key words; Three Gorges Project, Yangtze River flood discharge capacity to change into the Han river regulation

三峡 郦道元 自三峡七百里中，两岸连山，略无阙处；重岩叠嶂，隐天蔽日，自非亭午分，夜不见曦月。 至于夏水襄陵，沿溯阻绝。或王命急宣，有时朝发白帝，暮到江陵，其间千二百里，虽乘奔御风，不以疾也。 春冬之时，则素湍绿潭，回清倒影。绝巘多生怪柏，悬泉瀑布，飞漱其间。清荣峻茂，良多趣味。 每至晴初霜旦，林寒涧肃，常有高猿长啸，属引凄异，空谷传响，哀转久绝。故渔者歌曰：“巴东三峡巫峡长，猿鸣三声泪沾裳！” 译文： 从三峡七百里中，两岸高山连绵不绝，没有一点中断的地方；重重的悬崖，层层的峭壁，如果不是正午和半夜，就看不见太阳和月亮。 到了于夏天江水漫上丘陵的时候，下行和上行的航路都被阻绝了。有时遇到皇帝有命令必须急速传达，早晨从白帝城出发，傍晚就到了江陵，这两地可是相距一千二百多里呀！即使骑上快马，驾着风，也没有这样快。 到了春天和冬天的时候，雪白的急流，碧绿的潭水，回旋着清波，倒映着各种景物的影子。高山上多生长着姿态怪异的柏树，悬泉和瀑布在那里飞流冲荡。水清，树荣，山高，草盛，真是妙趣横生。 每逢初晴的日子或者结霜的早晨，树林和山涧显出一片清凉和寂静，高处的猿猴放声长叫，声音持续不断，异常凄凉，空荡的山谷里传来猿叫的回声，悲哀婉转，很久才消失。所以三峡中的渔民唱到：“巴东三峡巫峡长，猿鸣三声泪沾裳！”
