Preface

Geotechnical Engineering, literally translated as “geological technology engineering”, which is a new technical system established by European and American countries on the basis of civil engineering practice in the 1960s. It is a subject that mainly studies engineering issues of rock mass and soil mass. This book mainly introduces geotechnical engineering and geological exploration technology.
         Engineering exploration technology is an important means of construction engineering exploration, which directly serves foundation and the design of foundation engineering. The use of reasonable exploration methods is the key to ensuring the safety and stability of construction projects and the rationality of technology and economy. The editors and their teaching team summarized years of experience in teaching, scientific research, and practice, based on the principle of equal emphasis on practical technology and theoretical foundation, coordinated the relationship between basic theory and modern technology, and absorbed advanced production equipment and production technology. The editors coordinate the content of each chapter to make it closer to production practice.
      Geotechnical engineering is an interdisciplinary subject, which is widely used in highways, railways, bridges, tunnels, dams, airports, industrial and civil buildings and other fields. On the basis of prerequisite courses such as soil mechanics, foundation engineering and engineering geology, students have a comprehensive, systematic and in-depth understanding of the basic knowledge, theories and methods of geotechnical engineering through the study of this course, so that they can solve the practical problems of geotechnical engineering. On this basis, they can engage in exploration, design and construction of geotechnical engineering, and have certain research and development capabilities.

前 言

岩土工程（Geotechnical Engineering），直译为“地质技术工程”，是欧美国家于 20 世纪 60 年代在前入土木工程实践的基础上建立起来的一个新的技术体系，它主要是研究岩体和土体工程问题的一门学科。本书主要介绍了岩土工程与地质勘查技术。
        工程勘察技术是建设工程勘察的重要手段，直接服务于地基和基础工程设计。采用合理的勘察技术手段是确保建设工程安全稳定、技术经济合理的关键。本书结合了编者及其教学团队的多年教学、科研、实践的经验，以实用技术及理论基础并重为原则， 协调好基础理论与现代科技间的关系， 吸收先进的生产设备和生产工艺，统筹安排各章内容，使教材内容更能贴近生产实践。
        岩土工程是多门学科交叉的边缘学科，在公路、铁路、桥梁、隧道、堤坝、机场、工业与民用建筑等领域广泛应用。在土力学、基础工程和工程地质等先修课程基础上，学生通过本课程的学习，对岩土工程的基本知识、理论和方法有全面、系统和深入地了解， 使之具有解决岩土工程实际问题的能力， 能从事岩土工程的勘察、设计和施工，并具有一定的研究和开发能力。
