一、前言 作用在扶壁墙土压力计算理论的改进问题,至今仍未解决,目前,习用的方法是假定扶壁尾板末端垂面假想墙背上的主动土压力等值地传递到立板上(即朗金土压力的计算方法);对于底板,则用其上载压力(包括填砂自重和面载)为垂直土压力。黄埔新港二期工程扶壁码头的土压力就是采用上述方法计算的。为了探讨填土在扶壁各构件上土压力的分布规律,曾对该工程进行过原体(即原型,下同)观测和室内模型试验研究工作。
I. INTRODUCTION The improvement of the earth pressure calculation theory for the buttress wall is still unresolved. At present, the conventional method is to assume that the active earth pressure on the back of the imaginary wall at the end of the vertical wall of the buttress is equivalent to the vertical plate. Upper (that is, the calculation method of Lange earth pressure); for the soleplate, use its loading pressure (including sand loading weight and surface load) as the vertical earth pressure. The earth pressure of the wharf of Whampoa New Port Phase 2 project was calculated using the above method. In order to investigate the distribution law of earth pressure on the members of the buttress, the original (ie, prototype, the same below) observations and indoor model tests were performed on the project.
