随着我国社会主义革命和建设的飞跃发展,国家对港口建设速度和工程质量的要求日益提高。为了不断的提高设计效率与设计质量,并使设计人员从繁琐的计算工作中解放出来,根据中央关于积极推广电子技术和计算机的应用指示精神,在港口建设中,如何积极推广应用电子计算技术,已为大家关怀和重视。为此,交通部一九七三年即提出了“电子计算技术在筑港工程中的应用”的研究课题。为更好的开展此项工作,一九七四年根据部的指示精神,曾组织调查组对部属各航务工程局和航道局以及水运工程的设计、施工、管理中的计算问题,进行了调查研究。在此基础上,确定先就高桩码头、船坞等结构物及地基问题编写一批通用程序。此外,为了摸索经验,还就施工管理问题编写了少量程序。由于条件的限制,目前所进行的工作,只限于解决那些在设计、施工中经常遇到的,计算繁琐的某些问题,对某项计算内容而言,尽量选取目前各单位习惯采用的方法,以及一些比较先进的方法,以供选取采用。为完成这项工作,在交通部的领导和关怀下由上海船舶运输科学研究所、部属第一、二、三、四航务工程局、水运规划设计院、南京水利科学研究所等单位抽调专人,组成程序编写小组,开展这方面的工作。所有程序都是使用上海船舶运输科学研究所的 DJS-6型电子计算机进行调试及计算。同时均以一定的方法检验其正确性,或与手算结果相比较,或与精确解相比较。这里首先发表“用截面法计算弹性地基梁”等六个计算通用程序,其余的将陆续编写发表。由于我们的经验不足,谬误不当之处在所难免,尚希读者批评指正。
With the rapid development of socialist revolution and construction in our country, the requirements of the state for the speed of port construction and the quality of construction have been increasingly raised. In order to continuously improve design efficiency and design quality and free designers from cumbersome calculation work, according to the directive of the central government on actively promoting the application of electronic technology and computers, how to actively popularize the application of electronic computing technology in port construction, Has been for everyone care and attention. To this end, the Ministry of Communications in 1973 proposed a “research on the application of electronic computing technology in Hong Kong” project. In order to better carry out this work, in accordance with the directives of the Ministry, in 1974, a survey team was organized to investigate the calculation of design issues in the design, construction and management of subordinates’ navigation and navigation boards and waterway projects the study. On this basis, we will first make a number of general procedures for the construction of piled wharfs, docks and other structures and foundations. In addition, in order to explore the experience, a small amount of procedures were also written on construction management issues. Due to the limitations of the conditions, the work currently carried out is only limited to solving some problems frequently encountered in design and construction and complicated in calculation. In terms of a calculation, we should try our best to select the methods that are commonly used by various units at present, As well as some more advanced methods for selection and adoption. In order to accomplish this task, under the leadership and care of the Ministry of Communications, Shanghai Ship Transportation Research Institute, subordinate offices of the First, Second, Third and Fourth Navigation Engineering Bureaus, the Waterway Planning and Design Institute, Nanjing Water Resources Research Institute, Composition of the program writing team to carry out this work. All programs are commissioned and calculated using the DJS-6 electronic computer at the Shanghai Institute of Shipbuilding Science. At the same time, they are verified by a certain method, or compared with the result of manual calculation or compared with the exact solution. Here first published “Calculated using cross-section method of elastic foundation beam” and other six calculation of general procedures, the rest will be published one after another. Because of our lack of experience, fallacious mistakes are inevitable, but still hope readers criticize and correct.
