一、导言板桩碼头計算,几十年来一直采用Blum-Lohmeyer法。按此法計算之結果偏于保守,造成材料的浪費。此法的主要缺点之一,是忽視板桩变形特点对土压力分布的影响。本世紀廿年代以来,各国曾对板桩擋土墙計算問題进行过相当广泛的研究,提出的研究报告不下二百篇,計算方法計廿余种,唯研究成果用于工程实践中者不多。德国从事于板桩模型試驗研究最早,继而美英两国亦进行了不少模型試驗和现场观測。近七八年来,研究重心轉至苏联,模型試驗和原型試驗均具相当规模。此外,日本、丹麦、波兰、比利 I. INTRODUCTION The sheet-pile wharf calculation has been using the Blum-Lohmeyer method for decades. The results calculated according to this method tend to be conservative, resulting in material waste. One of the major drawbacks of this method is the neglect of the effect of the deformation characteristics of the sheet pile on the distribution of the earth pressure. Since the early twentieth century, various countries have conducted extensive research on the calculation of the retaining wall of sheet piles, and no less than 200 research reports have been submitted. The number of calculation methods is more than one, and only the research results are used in engineering practice. . Germany was engaged in the first research of sheet pile model test, followed by the United States and the United Kingdom also conducted a number of model tests and on-site observations. In the past seven or eight years, the focus of research has shifted to the Soviet Union. Both model tests and prototype tests are of considerable scale. In addition, Japan, Denmark, Poland, Billy
