| 中文摘要: |
| 利用轻便固结仪与压缩仪试验研究了不同状态(即不同的含水量、干密度、竖向压力)下膨胀土的膨胀量、膨胀力特性.在试验的基础上,对膨胀土的膨胀变形规律进行了初步探讨,并由此建立膨胀量与含水量、膨胀力与含水量及干密度之间的相关关系式. |
| 英文摘要: |
| This paper studies the characteristic of expansive soil s expanding quantity and expanding pressure under different state (namely different water content、dry density and vertical pressure) using hardiness concretion instrument and compress instrument. On the basis of experimentations, this paper investigates primarily the expansive stain rule of unsaturated expansive soil. As a result this paper establishes interrelated expressions of expanding quantity vs water content、expanding pressure vs water content and dry density, which have reference and application value. |
