【摘要】：近年來我國經(jīng)濟(jì)不斷發(fā)展,國內(nèi)外物資流通日益頻繁,促使航運(yùn)業(yè)蓬勃發(fā)展。港口作為貨物內(nèi)外貿(mào)主要節(jié)點(diǎn),對沿海經(jīng)濟(jì)具有重要貢獻(xiàn)。航道是沿海港口的重要組成部分,其通航寬度直接影響著港口通過能力,進(jìn)而成為影響港口經(jīng)濟(jì)的關(guān)鍵因素。科學(xué)地確定航道通航寬度是提高港口作業(yè)效率、保證船舶通航安全、提升港口經(jīng)濟(jì)發(fā)展的重要保障。 近年來隨著港口建設(shè)的突飛猛進(jìn)及船舶大型化趨勢的不斷發(fā)展,港址的選擇逐漸向深水區(qū)發(fā)展。深水區(qū)具有浪大流急的特點(diǎn),使設(shè)計與施工困難,較強(qiáng)的橫流會使船舶操控難度增加,降低通航安全,因此對航道通航寬度提出了更高的要求,然而為節(jié)約疏浚成本、滿足大型船舶進(jìn)港需求,國內(nèi)外已有眾多港口將港址選在受強(qiáng)潮流(橫流大于1.0m/s)影響較大的自然條件下。 我國現(xiàn)行規(guī)范JTS165-2013《海港總體設(shè)計規(guī)范》中在橫流流速超過1.0m/s的情況下,并沒有具體規(guī)定船舶漂移倍數(shù)及風(fēng)、流壓偏角的具體取值,一定程度上并不適合強(qiáng)潮流港區(qū)的航道通航寬度設(shè)計。 本文以我國《海港總體設(shè)計規(guī)范》、美國PIANC《進(jìn)港航道設(shè)計導(dǎo)則》及日本《港灣の施設(shè)の技術(shù)上の基準(zhǔn)·同解說》為研究對象,選取散貨船、集裝箱船、油船為研究船型,以橫流、航速、船舶噸級為主要影響因素,分別計算出不同國家規(guī)范對應(yīng)的航道通航寬度值,運(yùn)用Origin軟件進(jìn)行分析,總結(jié)出國內(nèi)外計算方法之間的差異,分析導(dǎo)致差異的因素,并提出強(qiáng)潮流影響下航道通航寬度計算的相關(guān)建議。 本文同時分析了不同因素(如橫流、航速、噸級等)對各國規(guī)范關(guān)于航道通航寬度設(shè)計的影響程度,總結(jié)出多種因素影響下各國規(guī)范航道通航寬度計算值的大小排序,并得出單一因素變化對不同計算方法的影響,為我國規(guī)范在航道通航寬度設(shè)計方面的完善提供建議,為相關(guān)部門提供科學(xué)依據(jù),為未來強(qiáng)潮流港區(qū)港口建設(shè)提供決策依據(jù),進(jìn)而使航運(yùn)業(yè)得到長遠(yuǎn)發(fā)展。
[Abstract]:In recent years, with the development of economy and the frequent circulation of materials at home and abroad, the shipping industry is booming. As the main node of domestic and foreign trade, port plays an important role in coastal economy. The channel is an important part of the coastal port, and its navigation width directly affects the port passing capacity, and then becomes the key factor affecting the port economy. Determining the width of navigation channel scientifically is an important guarantee to improve the efficiency of port operation, ensure the safety of ship navigation and promote the development of port economy. In recent years, with the rapid development of port construction and the continuous development of ship's large scale, the choice of port site is gradually developing to deep water area. The deep water area has the characteristic of big wave and large current, which makes the design and construction difficult, and the stronger cross current will increase the difficulty of ship handling and reduce the navigation safety. Therefore, it puts forward higher requirements for the width of navigation channel, but in order to save the dredging cost, To meet the needs of large ships, many ports at home and abroad have chosen port sites under natural conditions affected by strong currents (cross current > 1.0 m / s). The current code of JTS165-2013 (General Design Code for Ports) in our country does not specify the specific value of drift multiple, wind and deviation angle of flow pressure when the velocity of cross flow exceeds 1.0m/s. To some extent, it is not suitable for the channel width design of strong tidal current port area. This paper takes China's General Design Code for Ports, American PIANC's guidelines for Design of entry Channel and Japan's explanation of Technical Standards for Port installation as the research objects. Bulk carriers, container ships and oil tankers are selected as the study ship types, and the transverse flow is used as the research object. The speed and tonnage of ships are the main influencing factors. The navigable widths corresponding to different national codes are calculated respectively. The differences between domestic and foreign calculation methods are summarized by using Origin software, and the factors leading to the differences are analyzed. Some suggestions on the calculation of navigation width under the influence of strong tidal current are put forward. At the same time, this paper analyzes the influence of different factors (such as crosscurrent, speed, tonnage, etc.) on the design of navigable width in different countries, and sums up the order of the calculated values of navigable width under the influence of many factors. The influence of single factor change on different calculation methods is obtained, which provides suggestions for the improvement of navigation width design of navigation channel in our country, provides scientific basis for relevant departments, and provides decision basis for port construction in future strong tidal current port area. Then make shipping industry get long-term development.
