Abstract:小时候父辈就教导 :国家科学技术不强 ,只能遭受外国欺凌。为了报效祖国 ,大学里先学航空想造飞机打日本 ,其实哪有那么简单。学了 2年多 ,没有经济来源 ,无奈只有放弃“上天”梦想 ,改为“入地” ,学了采矿工程。抗日战争期间 ,全国只有一个油矿 ,于是和 8位同学商议好 ,毕业以后 ,“西出阳关”去玉门。到了那里我们大吃一惊 ,所有的设备机器全是进口的 ,还有一批留学回国人员 ,唯一奇缺的是年青的学子。于是我们分到了钻井、采油、机械、炼油等部门 ,勤奋地学习了不少新知识。

Abstract:The present calculation theory of pile settlement can neither describe the complexity of the pile soil system nor meet demands in all aspects of application. To solve this problem, this paper presented a practical calculation method of piles settlement after reasonable simplifications made to the present calculation theory according to the actual facts of medium to super long bored piles. The case study shows that the method can better forecast piles settlement.
