Highway engineering construction is closely related to all aspects of our living environment. It can be said that highway construction is an important cause related to people’s livelihood, and its development degree plays an important role in social development. Therefore, we should attach importance to highway construction in China, improve the coverage rate of highway, and attach importance to the quality of highway construction, strengthen the construction of highway engineering to facilitate our life.

  At present, the scale of construction projects is expanding day by day, and the types are increasingly diverse, showing a vigorous development momentum. Throughout the country, tens of thousands of high-rise buildings have sprung up. The rapid development of highway and railway construction has made remarkable achievements. The crisscross road network and railway network continue to extend and improve, which effectively promotes the sustained, rapid and healthy growth of the national economy. For the whole construction industry, improving the technical level and professional skills of construction personnel can effectively improve product quality and social benefits. For the construction personnel, improving their professional quality, especially some high-tech operation level, can greatly improve labor production efficiency, reduce labor intensity, speed up project progress, and reduce safety accidents.

  The effective management of highway engineering is an important work in the project, which plays a positive role in the control and evaluation of project quality, as well as speeding up the project progress and reducing the project cost. Highway management is also complex, with the rapid development of China’s economy, the role of highway in the process of national economic development is becoming more and more important, the country’s investment in highway is increasing, so it is very necessary to strengthen the management and practical analysis of highway engineering.

公路工程建设与我们生活环境的方方面面都有着密切的关联，可以说，公路建设是关系到民生的一项重要的事业，其发展程度对于社会的发展有着重要的作用，因此我们要重视我国的公路建设，提高公路的覆盖率，重视公路的建设质量。加强对公路工程的建设，便利我们的生活。
       当前，建设工程的规模日益扩大，种类日益繁多，呈现出蓬勃发展的势头。纵观全国，数以万计的高楼拔地而起，公路、铁路建设发展迅猛，成就斐然，纵横交错的公路网和铁路网不断延伸、完善，有力地推动着国民经济持续快速健康增长。对于整个建设行业来说，提高施工人员的技术水平和专业技能，可以有效地提高产品质量和社会效益。对于施工人员来说，提高自身的专业素质，特别是一些高技术含量的操作水平，可以大大提升劳动生产效率、降低劳动强度、加快工程进度、减少安全事故。
       公路工程有效管理是工程当中的一项重要工作，其对工程质量的控制、评定以及加快工程进度、降低工程造价都起着积极的作用。公路中的管理环节也是纷繁复杂的，随着我国经济的快速发展，公路在国家经济发展过程中的作用越来越重要，国家对公路的投资越来越大，因此加强对公路工程的管理与实务分析，就显得非常有必要。

  With the increasing development of economic globalization, the requirements for port and waterway engineering technology are more rigorous in order to adapt to the economic development. The construction of China’s economy is increasingly prosperous and develops into various forms. At the same time, China has also made breakthroughs in the field of foreign trade. As the window of China’s foreign trade, port and waterway plays an important role in promoting the national economic development and regional prosperity. Therefore, port and waterway engineering construction attract more and more attention of the society, and the technology applied in port and waterway engineering becomes more and more standardized. In recent years, China has invested more and more manpower and material resources in port and waterway engineering, which has a great impact on the continuing development of foreign trade.

  As the essential infrastructure of foreign trade, port and waterway highly promotes the national and regional development. Therefore, it has been paid more and more attention by the country and the people; its technical construction and management have to meet the higher and higher requirement offered by the people. This book gives a brief exploration, analysis and interpretation in the field of port and waterway engineering, mainly introduces the port management and waterway engineering which could provide theoretical support and reference experience for the construction of port and waterway engineering in the future.

  In view of the vast contents of port and waterway engineering and the limitation of compilers’ abilities, the content of the book may be inappropriate in some parts. Readers who use this textbook are welcome to criticize and correct the mistakes and deficiencies so that it could be further revised and supplemented in the future.

       鉴于港航工程内容浩瀚，编写人员水平有限，内容难免失当。欢迎使用本教材的读者，对其中的错误与不足，提出批评指正，以便今后进一步修改补充。

At present, our country has entered a new development stage of building a well-off society in an all-round way. With the gradual establishment of the socialist market economic system, people’s moral concepts and behavior patterns have changed profoundly. While great achievements have been made in the construction of spiritual civilization and material civilization, due to complicated historical reasons, there are still serious breaches of trust in social and economic life, such as malicious debt evasion, contract breach, debt default, tax evasion, smuggling and foreign exchange evasion, commercial fraud, counterfeit and shoddy, financial distortion, violation of financial discipline. These dishonest behaviors are still prominent, disrupting the social and economic order, damaging the interests of consumers, and affecting the healthy development of the national economy and the international image of China.

The socialist market economy is both a legal economy and a credit economy. Credit is the cornerstone of a modern market economy. Without credit, there is no order, and the market economy cannot develop healthily. The establishment of a social credit system is a fundamental measure to rectify and standardize the order of the market economy, as well as an important measure to improve the socialist market economic system.
    Due to the limited level of the author and the limited time, it is unavoidable to have some deficiencies in this book. Experts and readers are welcome to criticize and correct.
