连云港内河道疏浚工程二区岸坡稳定性分析和护岸挡墙初步设计.doc

摘要
连云港港是长三角主要港口和江苏最大海港,是苏北和中西部最经济便捷的出海口、新亚欧大陆桥东桥头堡，是以腹地内集装箱运输为主并承担亚欧大陆间国际集装箱水陆联运的重要中转港口。随着经济的发展，连云港的航运事业将会有更大的发展，在这一过程中，河道疏浚成为一个不得不面对的问题。河道疏浚要考虑方方面面的因素，本文主要集中讨论河道清理后的岸坡工程设计。
本文在开篇讲了连云港的地理位置，自然地理条件，气象水文，对本工程在连云港河道疏浚工程中的重要性做了简略介绍。然后讲了本工程护岸部分地形地貌，区域地质构造，地层，水文地质等工程地质条件，以便为下一步的工作打好基础。在第四章里，讨论了护岸部分的岩土特性，对护岸部分岩土进行了分层描述，初步讨论了护岸部分的全新统海陆交互相地层结构特征，通过对户岸部分的岩土特性讨论，厘清了本护岸存在的工程地质问题，明确了后面几章要解决的问题。从第五章，开始进入护岸工程的设计，讲了护岸工程设计的条件，包括护岸工程设计的依据规范和护岸工程设计的使用数据。鉴于在护岸工程设计中，岸坡稳定性分析的重要性，本文单独分出第六章，对岸坡稳定性进行了专门讨论，采用毕肖普条分法分析了岸坡稳定性，然后重点分析了影响岸坡稳定性的因素。第七章的重点是讨论挡土墙的设计，首先根据勘察资料讨论了挡土墙的型式，所用材料，再采用理正软件进行挡土墙设计，然后在用理论公式做了一系列验算，验算结果全部符合要求，最后给出了沉降缝和排水设施的设计。
本文的核心部分是通过对护岸部分工程地质条件的论述，提出了在河道疏浚时岸坡的稳定性问题，以及由此引发的一系列工程地质问题，随后对这些问题中的主要部分做了集中分析和解决。本文的稳定性分析和挡土墙设计均采用理论计算和理正软件计算相结合的方式。

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.
