連云港內(nèi)河道疏浚工程二區(qū)岸坡穩(wěn)定性分析和護(hù)岸擋墻初步設(shè)計(jì)

摘要
連云港港是長(zhǎng)三角主要港口和江蘇最大海港,是蘇北和中西部最經(jīng)濟(jì)便捷的出?？?、新亞歐大陸橋東橋頭堡，是以腹地內(nèi)集裝箱運(yùn)輸為主并承擔(dān)亞歐大陸間國(guó)際集裝箱水陸聯(lián)運(yùn)的重要中轉(zhuǎn)港口。隨著經(jīng)濟(jì)的發(fā)展，連云港的航運(yùn)事業(yè)將會(huì)有更大的發(fā)展，在這一過(guò)程中，河道疏浚成為一個(gè)不得不面對(duì)的問(wèn)題。河道疏浚要考慮方方面面的因素，本文主要集中討論河道清理后的岸坡工程設(shè)計(jì)。
本文在開(kāi)篇講了連云港的地理位置，自然地理?xiàng)l件，氣象水文，對(duì)本工程在連云港河道疏浚工程中的重要性做了簡(jiǎn)略介紹。然后講了本工程護(hù)岸部分地形地貌，區(qū)域地質(zhì)構(gòu)造，地層，水文地質(zhì)等工程地質(zhì)條件，以便為下一步的工作打好基礎(chǔ)。在第四章里，討論了護(hù)岸部分的巖土特性，對(duì)護(hù)岸部分巖土進(jìn)行了分層描述，初步討論了護(hù)岸部分的全新統(tǒng)海陸交互相地層結(jié)構(gòu)特征，通過(guò)對(duì)戶(hù)岸部分的巖土特性討論，厘清了本護(hù)岸存在的工程地質(zhì)問(wèn)題，明確了后面幾章要解決的問(wèn)題。從第五章，開(kāi)始進(jìn)入護(hù)岸工程的設(shè)計(jì)，講了護(hù)岸工程設(shè)計(jì)的條件，包括護(hù)岸工程設(shè)計(jì)的依據(jù)規(guī)范和護(hù)岸工程設(shè)計(jì)的使用數(shù)據(jù)。鑒于在護(hù)岸工程設(shè)計(jì)中，岸坡穩(wěn)定性分析的重要性，本文單獨(dú)分出第六章，對(duì)岸坡穩(wěn)定性進(jìn)行了專(zhuān)門(mén)討論，采用畢肖普條分法分析了岸坡穩(wěn)定性，然后重點(diǎn)分析了影響岸坡穩(wěn)定性的因素。第七章的重點(diǎn)是討論擋土墻的設(shè)計(jì)，首先根據(jù)勘察資料討論了擋土墻的型式，所用材料，再采用理正軟件進(jìn)行擋土墻設(shè)計(jì)，然后在用理論公式做了一系列驗(yàn)算，驗(yàn)算結(jié)果全部符合要求，最后給出了沉降縫和排水設(shè)施的設(shè)計(jì)。
本文的核心部分是通過(guò)對(duì)護(hù)岸部分工程地質(zhì)條件的論述，提出了在河道疏浚時(shí)岸坡的穩(wěn)定性問(wèn)題，以及由此引發(fā)的一系列工程地質(zhì)問(wèn)題，隨后對(duì)這些問(wèn)題中的主要部分做了集中分析和解決。本文的穩(wěn)定性分析和擋土墻設(shè)計(jì)均采用理論計(jì)算和理正軟件計(jì)算相結(jié)合的方式。

ABSTRACT
Lianyungang  port  is delta  main ports and  Jiangsu largest seaport, it is the most economical and convenient in North and Midwest to the sea, the new Eurasian Continental Bridge bridgehead, is a hinterland container transport between Asia and Europe-based and assume an important international container transit port land and water transport. With economic development, the shipping industry in Lianyungang, will have greater evelopment.  In this process, channel dredging will be a problem that we have to face. River dredging  must consider all aspects of the factors. This article focuses mainly on river clean-up of the bank slope engineering.
This article begins with talk of the Lianyungang location, geography, meteorology and hydrology,on the project in Lianyungang, the importance of river dredging done in the brief introduction.Then talked about some of the bank protection works topography, regional geological structure, stratigraphy, hydrogeology, engineering geological conditions, etc, in order to lay the foundation for further work.In the fourth chapter, discusses on some of the geotechnical characteristics of bank protection on the part of the rock revetment was layered description, a preliminary discussion of some of the new revetment and sea delivery system structural characteristics of each stratum.On shore part of the geotechnical characteristics of households to discuss and clarify the existence of the bank protection engineering geological problems, specifically the later chapters to solve the problem.From the fifth chapter,we entered design of bank protection works, talking about the design of bank protection works, including an engineering design based on revetment bank protection engineering design specifications and use of data.View of the revetment slope stability analysis in the importance of engineering design,Chapter VI of this paper are listed in a separate slope stability was devoted, by Bishop slice method slope stability analysis,and then analyzed the factors that affect slope stability.Chapter VII of the discussion focused on the design of retaining walls, first discussed the retaining wall according to survey data of the type, materials used, more, I use software to design retaining walls.And then do a series with the theoretical formula checking, checking all the results meet the requirements. Finally,the design of the settlement joint and  drainage facilities was given.
Core part of this article is part of the project through the revetment discusses the geological conditions,when the proposed dredging the river bank slope stability problems, and triggered a series of engineering geological problems, then these questions do focus on the main part of the analysis and solution.This stability analysis and design of retaining walls are used theoretical calculations and the reasons are a combination of software.
