- 摘要:
- 针对在苏丹炼厂扩建土建工程中遇到的气候高温干旱、地质结构复杂、社会依托条件落后等不利条件以及设计中存在的问题,提出了解决方法。包括完善设计、发挥程序文件的作用、采用抗裂效果好的混凝土外加剂以及保温、保湿措施,有效防止了大体积混凝土裂缝的产生,采用加筋方法提高了牛粪砖砌体强度,另外,通过试验解决了地基土的膨胀性和基础的二次灌浆问题。
In order to overcome the disadvantages such as high temperature and drought climate, complex geological structure and poor social support condition as well as the problems existing in the design, some solutions are provided including consummating design, bringing program files into play, applying good concrete additives of crack resistance and adopting temperature and moisture preservation measures to prevent crack occurrence of bulk concrete, adopting reinforcement method to increase masonry strength of cow-dung bricks. Also, the problems of dilatability of foundation soil and secondary foundational grouting are solved through experiments and tests.2007,06(06): 72-74 收稿日期：2007-3-12分类号：TU746.3;TU375.6作者简介：石全喜(1966-), 男, 山西芮城人, 工程师, 1989年毕业于江汉石油学院工民建专业, 一直从事现场炼化建设工作.参考文献：
