【摘要】：近些年來，隨著港口在國民經(jīng)濟中的地位一步一步地提升，港口應用功能的不斷擴展，其中航道工程是港口發(fā)展的基石，港口管理工作的重點和難點就是維護航道的正常通航水深，解決航道泥沙淤積問題。一個地區(qū)建立港口的理想之地當然是優(yōu)良的港灣和天然的深水岸段。然而由于沿海地區(qū)地理位置的制約，我國一部分沿海地區(qū)雖然處于對建立港口不利的砂質(zhì)、粉砂及淤泥質(zhì)海岸，在地區(qū)經(jīng)濟發(fā)展的迫切需求下，隨著我國經(jīng)濟實力以及技術(shù)水平的不斷發(fā)展進步，在這些地區(qū)建立港口已經(jīng)非常的普遍。我國對砂質(zhì)、淤泥質(zhì)海岸的研究比較深入，而隨著驟淤現(xiàn)象的出現(xiàn)使得對粉砂質(zhì)海岸的研究也逐漸重視起來，與前兩種海岸相比起來，粉沙質(zhì)海岸的研究比較膚淺。黃驊港的海岸性質(zhì)屬于典型的粉砂質(zhì)海岸。 由于影響航道淤積的因素具有強非線性、隨機性、時變性及高度的不確定性等特點，這些都給航道清淤及淤積預測帶來了極大的困難。而建立在粉砂質(zhì)海岸上的航道工程由于本身砂質(zhì)的原因，加上環(huán)境因素，人為因素的作用，這些航道的淤積問題更是引起了人們的廣泛關(guān)注。嚴重的淤積，不僅增加航道正常水深維護的巨額投資，，而且對過往航道船舶的安全靠泊及通航造成嚴重的影響。本文重點從以下幾個方面對黃驊港航道進行了研究： (1)分析了黃驊港的海岸形成過程、海岸特性及港區(qū)的自然條件。 (2)歸納了黃驊港綜合港區(qū)航道淤積的因素，分析了各個因素對黃驊港綜合港區(qū)航道產(chǎn)生淤積的原因。 (3)運用了具有全局最優(yōu)和良好泛化能力的SVM模型，其模型參數(shù)由微粒群算法PSO進行優(yōu)化，建立黃驊港綜合港區(qū)航道的PSO-SVM淤積預測模型，并對已有的淤積量的數(shù)據(jù)樣本分組進行了訓練與預測。該模型中不僅考慮了大風的影響，還考慮了地形的影響，從而為航道淤積預測模型的研究提供了一種新思路、新方法。 (4)PSO-SVM淤積預測模型具有良好的擬合性，對于給定的大風強度，可以通過PSO-SVM模型對航道的重點淤積里程段提前進行淤積量的預測，以便及時的安排作業(yè)船只的清淤計劃。 (5)結(jié)合航道的年淤積量分布及沿程水深圖對黃驊港綜合港區(qū)航道清淤船舶進行優(yōu)化清淤安排，并對黃驊港綜合港區(qū)現(xiàn)有清淤船舶清淤量提出建議，為黃驊港航道的優(yōu)化清淤提供指導作用。 (6)對本文研究的內(nèi)容進行了概況，對研究的不足進行了闡述，并對今后的研究重點進行了展望。
[Abstract]:In recent years, with the status of the port in the national economy step by step, the port application function continues to expand, among which waterway engineering is the cornerstone of port development. The key and difficult point of port management is to maintain the normal navigable depth of the waterway. The ideal place for a region to establish a port is, of course, an excellent harbour and natural deep waterfront. However, due to the geographical location of the coastal area, Although some coastal areas of China are in the sand, silt and silt coasts that are unfavorable to the establishment of ports, under the urgent need of regional economic development, with the continuous development of China's economic strength and technological level, The establishment of ports in these areas has become very common. In China, the study of sandy and muddy coasts has been more in-depth, and with the appearance of sudden siltation, the study of silty coasts has gradually been attached importance to, compared with the former two kinds of coasts. The coastal properties of Huanghua Port belong to the typical silty coast. Due to the strong nonlinear, randomness, time-varying and high uncertainty of the factors affecting the siltation of the channel, These have brought great difficulties to the prediction of siltation and siltation in waterways. However, waterway projects built on silty coasts are affected by their own sand quality, environmental factors and human factors. The siltation of these waterways has aroused widespread concern. Serious siltation not only increases the huge investment in the normal water depth maintenance of the waterway, And it has a serious impact on the safe berthing and navigation of vessels in the past waterway. In this paper, the waterway of Huanghua Port is studied from the following aspects:. The coastal formation process, coastal characteristics and natural conditions of Huanghua Port are analyzed. This paper sums up the factors of channel siltation in Huanghua Port Comprehensive Port area and analyzes the reasons for the siltation of each factor to the waterway of Huanghua Port Comprehensive Port area. The SVM model with global optimum and good generalization ability is used. The model parameters are optimized by the particle swarm optimization algorithm (PSO), and the prediction model of PSO-SVM siltation in the waterway of Huanghua Port integrated port area is established. In this model, not only the influence of strong wind, but also the influence of topography are considered in the model, which provides a new way and method for the study of channel siltation prediction model. The prediction model of PSO-SVM siltation has a good fit. For a given wind intensity, the PSO-SVM model can be used to predict the silt amount of the key silt mileage section of the waterway in advance, in order to arrange the dredging plan of the working vessel in time. (5) to optimize the arrangement of dredging vessels in the waterway of Huanghua Port integrated port area in combination with the annual siltation distribution of the waterway and along the Cheng Shui depth diagram, and to put forward some suggestions for the current desilting ship desilting capacity in the integrated port area of Huanghua Port. It provides guidance for optimizing silt clearing in Huanghua Port. The main contents of this paper are summarized, the shortcomings of the research are expounded, and the future research emphases are prospected.
