本文为上海软土强度试验资料的初步总结,包括四个部分:关于上海软土地基的天然强度;软土在固结过程中强度增长的规律;稳定分析中的几个问题;上海软土地基预压的一些经验。提出了上海地区自地表以下10～20米范围内天然强度的经验公式;分析了上海某厂22台油罐的充水预压资料;初步探讨了在加荷过程中软土地基的固结规律。从而提出了在软土地基上应考虑适应于固结速率的最佳设计这一观点,以减少工程投资费用。
This article is a preliminary summary of Shanghai soft soil strength test data, including four parts: the natural strength of soft soil foundation in Shanghai; the law of strength growth of soft soil during consolidation; several problems in stability analysis; Shanghai soft soil foundation Some experience with preloading. An empirical formula for natural strength in the range of 10 to 20 meters below the surface of the earth surface in Shanghai is proposed; the water preloading data of 22 oil tanks at a certain factory in Shanghai are analyzed; and the consolidation law of soft soil foundations during loading is preliminarily discussed. . Therefore, the viewpoint that the optimal design for the consolidation rate should be considered in the soft soil foundation is proposed to reduce the engineering investment cost.
