京长江四桥的技术标准高,施工难度大,质量要求严,自2008年底开工以来遇到许多新挑战、新考验。建设者勇于创新、精细管理,攻克了一个又一个难关,取得了多项技术创新,最终高质量、快节奏地完成了各个阶段的建设任务。南京长江四桥取得的科技创新成果如下:复杂地质条件下的“∞”字型地下连续墙基础设计施工技术根据南锚碇场区分布状况及基岩埋深浅且起伏大等地质特点,南锚碇在国首
The technical standards of the Fourth Yangtze River Bridge in Beijing are high, the construction is difficult and the quality is strict. Since the start of construction in late 2008, many new challenges and new tests have been encountered. Builders brave in innovation, fine management, capturing one after another difficulties, made a number of technological innovations, and ultimately high-quality, fast-paced to complete the construction tasks of all stages. Scientific and technological innovations made by Nanjing No.4 Bridge are as follows: Basic Design and Construction Technology for “∞” Typed Diaphragm Wall under Complicated Geological Conditions According to the distribution characteristics of south anchorage field and the geologic features of shallow and undulating ground bedrock, South Anchorage in the country first
