以下就是土木毕设网为大家精心整理的基坑工程设计中英文摘要范文。供大家学习。
拟建工程，地面以上6层，地下2层。总建筑面积69533m2，其中地上建筑面积为54330 m2，地下建筑面积为15203m2，建筑±0.00相当于绝对标高17.25m，基坑开挖深度8.50m。
结合本工程地质、环境、挖深等诸多因素确定安全可靠的支护方案；为基坑土方开挖和地下室施工创造一个安全干燥的施工环境；考虑到邻近坑边有建筑和道路（下设有水、电、气等管线），为确保安全，以“变形”控制设计。
本着“安全可靠、经济合理、技术可行、施工方便”原则，整个基坑采用一排钻孔灌注桩作挡土结构,一道钢筋混凝土支撑作为支撑结构体系。基坑西侧和北侧坳沟、暗塘处采用深层搅拌桩作止水帷幕。基坑内采用集水坑排水。

The design for foundation pit of national microstructure laboratory in Nanjing University
Abstract
The building of national microstructure laboratory in Nanjing University to be proposally constructed is 6-layer tall,including 2 basements.Its general construction area is 69533 square meters,containing 54330 square meters above the ground surface and 15203 square meters below the ground surface.The average level of the construction for 0.00,absolute level is 17.25 meters.The depth of excavation is 8.5 meters.
Considering of the geologic environment,excavation depth of the foundation pit,to create an safe and dry surroundings for the earth work and basement,we carry out the design in control of displacement deformation,in order to keep the main traffic roads and buildings safe and to arrange pipelines of water,electricity and coal gas below the surface.
According with fundamental technical standard,approaching safe reliability,the economical-reasonable and convenient construction and guaranteeing project time limit，we use nondisplacement piles as retaining structure,reinforced concrete bracing as bracing structure.In the western and northern parts of the foundation pit,we use deep churning piles as detaining water pile construct enclosed cut off trench.With the purpose of dewatering,we use sump.
Key words:Foundation pit;Bracing structure;Retaining structure;
Reinforced concrete bracing;Nondisplacement pile
