一、前言 新港船厂万吨船坞坞墙采用刚度较小的钢板桩结构,东侧采用混合式锚碇设备,坞室开挖时采用临时钢支撑。为掌握船坞结构的特性和板桩土压力分布规律,在坞室Ⅲ区的东侧设置观测仪器进行试验研究。通过试验,对有关工程问题作了改进,对有关理论问题有了进一步认识。
I. Foreword The Newton Shipyard’s 10,000-ton dock dock wall adopts a less rigid steel sheet pile structure with a hybrid anchorage equipment on the east side and a temporary steel support for the dock excavation. In order to grasp the characteristics of dock structure and the pressure distribution law of sheet piles, an observational instrument was set up on the eastern side of Dock III to carry out experimental research. Through experiments, the relevant engineering problems have been improved, and further theoretical understanding has been reached.
