环境岩土工程是岩土力学与环境科学密切结合的一门学科，其主要应用岩土力学的观点、技术、方法去解决和环境有关的岩土工程问题，为治理以及保护环境做贡献。涉及问题（1）：人类与自然环境之间的共同作用。这类问题主要由自然灾害引起，如温室效应、地震作用、土壤退化、洪水灾害、水位的变化、区域性特殊土的影响等。（2）人类的生活、生产以及工程活动引起的与环境之间的作用，其发生的主要原因是人类本身，如城市各种工业、商业以及生活垃圾、工业废水、废渣、废气等有毒有害物质对环境与生态的影响。

Environmental geotechnical engineering is a subject closely combining rock and soil mechanics with environmental science. It mainly applies the viewpoint, technology and method of rock and soil mechanics to solve the geotechnical engineering problems related to the environment, and makes contributions to the governance and environmental protection. Issues involved (1): the common role between human beings and the natural environment. Such problems are mainly caused by natural disasters, such as greenhouse effect, seismic effect, soil degradation, flood disaster, water level changes, the influence of regional special soil, etc.(2) The role between human life, production and engineering activities and the environment, the main reason for the occurrence of human beings themselves, such as various urban industrial, commercial and household garbage, industrial waste water, waste residue, waste gas and other toxic and harmful substances on the environment and ecology.
