摘　　要：随着经济的发展,交通的快速化改造,地下空间的应用也越来越多。恰当选取基坑支护形式会给整个工程的费用及工期带来很大的影响,因此,对深基坑支护的研究显得格外重要。本文以某下穿隧道基坑工程为例,阐述了基坑工程的土工原理及支护的一般类型,并根据其地质条件、周围环境的影响、支护结构的受力特点等因素,采用多种支护形式结合的方式。通过计算,给出了经济、合理、可行的施工方案。With the economic development and rapid transformation of transportation,the underground space has been applied widely.The proper selection of the form of foundation pit support will have a great impact on the cost and construction period of the whole project.Therefore,the study of deep foundation pit support is particularly important.In this paper,taking a tunnel foundation pit as an example,the geotechnical principle and general types of support are described.According to its geological conditions,the influence of the surrounding environment,the stress characteristics of the support structure and other factors,a variety of support forms are adopted.Through calculation,the economic,reasonable and feasible construction scheme is given.
