地下连续墙是近二十多年来在基础工程和地下工程中广泛应用的一项新技术。这项新技术对于解决施工困难、节省土方工程量、降低造价、加快施工进度等都有很大作用,它可以广泛地应用于地下铁道、地下停车场、地下油罐、下水道、房屋基础、桥梁基础、铁塔基础、设备基础、竖井、挡土墙、船坞、码头、堤坝等方面,尤其是在扩建和改建工程中,更具有其独特的优点。当前,我国许多部门为落实“抓纲治国”的战略决策,加快国民经济的发展速度,正在积极地研究采用和推广这项新技术。因此,我们组织了这一技术讲座,请国家建委建筑科学研究院建筑情报研究所的潘千里同志对这项新技术的施工工艺和设计计算方法作一较系统的介绍。讲座从本期起连续刊载。
Underground diaphragm wall is a new technology widely used in basic engineering and underground engineering in the past two decades. This new technology is very useful for solving construction difficulties, saving earthworks, reducing cost, and accelerating construction progress. It can be widely applied to underground railways, underground parking lots, underground oil tanks, sewers, building foundations, and bridge foundations. The foundation, equipment foundations, shafts, retaining walls, docks, wharves, embankments, etc., especially in the expansion and reconstruction projects, have their own unique advantages. At present, many departments in our country are actively studying the adoption and promotion of this new technology in order to implement the strategic decision to “grasp governance” and to accelerate the development of the national economy. Therefore, we organized this technical seminar and invited Comrade Qian Qianli of the Institute of Building Intelligence of China Academy of Building and Construction Sciences to make a systematic introduction to the construction process and design calculation method for this new technology. Lectures are published continuously from this issue.
