1855—1995年黄河下游山东河段河道冲淤厚度浅析

对山东黄河河道主槽、滩面冲淤情况计算分析表明，陶城铺以上河段１９３４－１９９５年在主槽淤积３．０－６．０ｍ，１８７５－１９９５年滩地淤积４．０－４．３ｍ；陶城铺－利津河段１８５５－１９９５年主槽淤积９．５－１４．３ｍ，１８７５－１９９５滩地淤积３．４－３．９ｍ；利津－渔洼河段１９６５－１９９５年主槽淤积１．３－３．０ｍ，１９６４－１９９５年滩地淤积０．３－０．７ｍ；渔洼以下河段１９７７－１９９５年

Analysis of Sedimentation and Scouring Depthes in Shandong Reaches of the Lower Yellow River from 1855 to 1995

Calculation and analysis of sedimentation and scouring in main channel and on beach of tile Yellow River in Shandong province demonstrate that there had been 3 to 6 meters sedimentation in the channels in the reaches above Taochengpu from 1934 to 1995, 4.0 to 4. 3 meters sedimentation on beaches from 1875 to 1995; 9. 5 to 14. 3 meters sedimentation in the channels of Taochengpu to Lijin from 1855 to 1995, 3 .4 to 3. 9 meters sedimentation on beaches from 1875 to 1995; 1. 3 to 3.0 meters sedimentation in the channels of Lijin to Yuwa from 1965 to 1995, 1. 0 to 2. 3 meters sedimentation on beaches from 1964 to 1995; and 0. 5 to 1.9 meters sedimentation in the channels of below Yuwa from 1977 to 1995, 0. 1 to 1. 0 meters on cormsponding beaches. Overall speaking, the speed of sedimentation in main channels is much more larger than that on beaches, therefore the disadvantageous river states of high channels, low beaches and dyke base are formed.
