堤壩建成后，圍堰仍然保留，用作主壩的護堤，西壩的護堤，向海的一面更安放了七千多塊每塊各重25噸的防波石，阻擋來自南中國海及太平洋海浪的沖擊。In order to eliminate the hidden trouble caused by storm runoff erosion, the mechanism of the storm runoff erosion on the slope surface of the yellow river dykes has been studied in this thesis. through the simulation rainfall experiments and field observations, the formation mechanism of storm runoff scouring, rills and sockets have been opened up. meanwhile the possible control measures have been suggested
為了防治黃河大堤由於暴雨徑流沖刷造成的不安全隱患，本文針對黃河大堤上的暴雨徑流侵蝕進行了實地設站觀測及室內模擬降雨侵蝕試驗，通過揭示大堤暴雨沖刷過程機理，查清水溝、水穴（浪窩）等的成因，提出相應的防治對策。This paper summarize the estuary sediment management methods also, analyze and the following aspects and give evaluations : estuary dredging and lead the flow, lead water to scour the river channel, build the xihekou reservoir, estuary gate deposition management, dike reinforced etc
本文還對河口泥沙的處理途徑和措施進行了概括總結，對河口疏浚與導流、引海水沖刷河道、建設西河口水利樞紐、攔門沙治理、人工有計劃改道和出漢、加高堤防和加固防護工程和挖河固堤工程等進行了分析評價。In the general design and analysis methods for problems of the breakwater stability, the concept of compositive safety factors is used usually. however, floodwater, storm wave and beach erosion as well as properties of soil medium are always random, which may have uncertainties
在防浪堤壩的設計中，傳統的安全性能分析方法採用綜合的安全系數概念，但洪水、風浪、河道沖刷、土力學特性等因子都是隨機性的，具有一定的不確定性。Protection : it can prevent riverbank from strong wind and heavy rain. besides, it can protect dam and the bottom of river and prevent the loss of sand
防護作用：防止堤巖受風，浪，雨的沖刷，並可用於護岸，護坡，護底，防止水土流失。This paper presents a method of probability analysis in order to develop the general design and analysis methods for problems of the embankment stability under random storm wave actions as well as with random properties of the embankment medium. the major purpose of this study is carry out modellings of ( 1 ) probability analysis for the problem of seepage stability of levee projects ; ( 2 ) probability analysis for the problem of erosion due to washout sediments from the embankment ; ( 3 ) numerical analysis for coastal evolution due to beach erosion under energy actions of storm wave
本文根據598084號年浙江省自然科學基金項目和g59901號國家教育部回國留學人員科研啟動基金項目的部分研究目標和研究內容的要求應用概率分析方法研究了在隨機風浪荷載作用下和築堤材料隨機性影響下防護堤壩抗滲流、抗沖刷穩定性的分析計算模型；用數值分析方法研究了在浪潮能量作用下岸灘侵蝕造成海岸演變問題的數學分析模型。A barrier that protects a harbor or shore from the full impact of waves
防波堤，防浪墻保護一個港口或海岸以防波浪沖擊的障礙物But before engineers redesign a single levee, they must consider a fundamental question : can the mississippi delta be restored as a lush, hardy buffer that can absorb surges and rising seas
不過在工程師重新設計一個單一堤防之前，必須先考慮一個基本的問題：密西西比三角洲能不能復育成一個繁茂且堅強的緩沖區，可以容納大浪和上升的海平面？The main problem is that near shore, a tsunami ' s actual size is masked by additional waves generated as the tsunami bounces off seawalls, wraps around islands, or sloshes back and forth in a bay ? all of which make for a very tangled signal
然而主要問題是當海嘯接近岸邊時，沖擊防波堤產生的巨浪，或是當它包圍島嶼、在海灣里來回所飛濺的浪花，都會造成非常紊亂的訊號，掩蓋海嘯的實際大小。The research presents that the reliability method based on the probability analysis for seepage and erosion stability of levee project is more scientific and more reasonable for seepage safety of dikes
