红粘土地区水泥土强度的试验研究
摘要:红粘土是亚热带气候条件下形成的一种特殊土质。含有红粘土的地基多具有上硬下软的特点,下部红粘土为天然地基软弱下卧层。采用深层搅拌法处理,可充分发挥上部硬塑红粘土的作用,形成复合地基。通过试验得到了水泥红粘土的基本力学参数。在对试验结果进行回归分析后,给出了水泥土强度的影响因素及其与强度的关系,以及不同水泥掺量、龄期水泥土之间的强度推算公式。
Abstract:This kind of soil is formed during the chemical weathering of carbonate rocks.It exhibits high water content and high plasticity. When structures are constructed on red day foundations, the soil often needs to be treated due to its soft properties, Although the method of mixing of rail and cement is commonly used to improve soft soil, intensive studies on its affect are relatively few. Unconfined compression tests are performed on the cemented red clay. The basic mechanics parameters of this kind cement soil can he got by experiment. After the regression analysis of the experimental result,it can he given that influence factors for cement soil strength and relation between it,and the strength calculate formulas of different cement contents and cure ages.
