Research Of New Embankment Wave Prefabricated Piece On Slope Protection And The Effect Of Wave

Dyke project is one of the major flood control engineering measures in the lake regions of China, the safety issues of levee engineering relates to the success or failure of flood control works and the lake district residents' life and property safety, directly. And the levee protection is the most important measure to ensure the safety of levee engineering, the embankment slope protection is a indispensable part of the levee protection.This research topic is derived from the science and technology project <Research of the embankment wave prefabricated piece on slope protection and the effect of wave in Poyang Lake area > of the Water Conservancy Bureau, Jiangxi Province. Because of prolonged affected by the Yangtze River Basin Flood, Frequent floods have been a serious threat to the Lake District and the surrounding area has been living and economic construction. Because of earlier time renovation, and the Low flood control standards, and restrictions on construction technology, Dyke becomes easy to be destroyed, Poyang Lake area dike reinforcement construction without delay. In order to solve the current problems in Lake Levee, From the aspects of Lake embankment prefabricated blocks slope protection, The main contents and conclusions are as follows:(1)This article first embarks from the forming mechanism and the factors of the wind and waves, through reading some related literatures, the factors to form waves and winds has been understandable, the mechanism of wave and breakwater slope has also been studied.(2)based on the research of existing wave slope protection's shape and wave effect, and combined with the actual situation of Poyang Lake dikes, three new wave energy dissipation precast concrete block revetment shapes has been designed targeted.(3)Based on the gravity similarity criterion we designed and performed the foreshore model test, analysis and summary the experimental data systematically. Through the comparison with the traditional smooth precast block revetment foreshore, it is indicated that the three new types of embankment precast concrete block revetment's body wave ability are obviously better than the traditional smooth precast block revetment.The three new types of lake embankment slope protection has a certain reference value for scientific research and engineering practice significance to the Lake dikes seepage and reinforcement project.
