摘要

本文介绍了城市环境下深基坑支护系统的设计。挖掘是在周围建筑物附近进行的,在施工过程中必须保证建筑物的结构稳定性。选取两排(17.00 m和18.25 m)岩土锚杆支撑的60 cm厚连续墙作为开挖支护体系。地下连续墙平面尺寸约为81x118 m,最大开挖深度10.5 m。设计连续墙的另一个挑战是地下水的存在,其最大水位约为5.8米深。为了确保在干燥条件下施工,在基坑底部设计了排水沟渠和水井系统。连续墙的设计符合欧洲规范7。

An example of the protection of a deep excavation in an urban environment
The paper presents the design of deep excavation support system in an urban environment. Excavation is carried out in the vicinity of surrounding buildings whose structural stability must be ensured during the execution of the construction works. The 60 cm thick diaphragm wall supported by the two rows (17.00 m and 18.25) of geotechnical anchors was selected as an excavation support system. The approximate floor plan dimensions of the diaphragm wall are 81x118 m, and the maximum excavation depth is 10.5 m. An additional challenge in designing the diaphragm wall is the presence of groundwater, whose maximum level is observed at a depth of approximately 5.8 m. In order to ensure the execution of construction works in dry conditions, a system of drainage trenches and wells is designed at the bottom of the pit. The diaphragm wall is designed in accordance with Eurocode 7.
