Study on the design method of the jack-up’s x-type cantilever allowable load nephogram

The extending of a cantilever and transverse moving of a drilling floor enable the jack-up to operate in several well positions after the Jack-up has pitched. The cantilever allowable load nephogram is the critical reference which can evaluate the jack-up＇s drilling ability, design the cantilever structure and instruct a jack-up manager to make the operations safe. The intent of this paper is to explore the interrelationships between the cantilever position, drilling floor and the loads including wind force, the stand set-back weight etc., through analyzing the structure and load characteristics of the x-type cantilever and the simplified mechanics model with the restriction of the maximum moment capacity of the cantilever single side beam. Referring to several typical position designs load values, the cantilever allowable load nephogram is obtained by using the suitable interpolation method. The paper gives a method for cantilever allowable load design, which is proved reliable and effective by the calculation example.     

简码扩充输入法原理及其应用

计算机处理的文本中重复出现的词组定义为简码，这有利于减少输入工作量，但一种编码法已定义了一定量的简码汉字，在一个编译系统里就无法再重定义。现考虑了一种ＷＰＳ与原有汉字输入法不矛盾的简码扩充输入法，可实时以简码形式定义词组，并有相应的译码软件翻译成汉字，方便了使用。     

天然地基上扩大基础基坑工程量计算

目前国内公路桥涵施工图设计中,对天然地基上扩大基础基坑工程量计算,基本按单体构造物形状向外沿按1:n的坡率放坡,形成倒置台体形状,粗略计算其体积。本文从施工角度出发,充分考虑施工各环节所发生的各部分工程量,总结出较精确的开挖基坑工程数量计算方法。
