目前,在国内外,关于胀缩土地基缩降量计算的方法还很少;关于胀缩土地基胀升量的计算方法却很多,但存在不少问题,甚至有些方法在某些地区根本无法应用。由于这个问题还没有很好地解决,致使目前的处理措施(不管是地基和基础方面的,还是上部结构方面的),都是凭定性地估计和主观的经验确定的,因而有成功的,有失败的,带有不少盲目性。本文论述了现有计算方法存在的一些主要问题,提出了解决这些问题的计算方法。本文 At present, at home and abroad, there are few methods for calculating the shrinkage and shrinkage of land bases; there are many calculation methods for the expansion and shrinkage of soil bases, but there are many problems, and some methods may not even be available in some regions. application. Since this problem has not been solved well, the current treatment measures (whether on the ground or in the foundation or in the superstructure) have been determined based on qualitative estimation and subjective experience, and thus have been successful. Failed, with a lot of blindness. This article discusses some of the major problems existing in existing computing methods and proposes a calculation method to solve these problems. This article
