水泥石灰复合改良膨胀土试验
Experimental Research on the Stabilized Lime-cement Expansive Soil
摘要
Abstract
The Eastern Route passes through the canals and pumping stations (the Sihong, Pizhou, and second Liulaojian stations) located in the central area of the northern Jiangsu Province, and the expansive soil may occur in these canals and stations. If the foundation of the pumping station is located on the expansive soil,the structure of the pumping station may have a risk to be destroyed during the operation of pumping because of the uneven-distributed expansion and shrinkage of the expansive soil. Another more important engineering problem in the Eastern Route of the South-to-North Water Diversion Project is the use of the excavated expansive soil during the construction of pumping stations and canals. For instance,more than 80,000 cubic-meter expansive soil was excavated at the second Liulaojian Station,and its storage requires a large area of land. On the other hand, the filling soil behind the retaining wall at the upstream and downstream of the diversion canal at the pumping station needs a large amount of applicable soiL The transformation of the excavated expansive soil to the filing soil behind the retaining wall is a project of comprehensive utilization. The paper studies this transformation using the stabilized method and the characteristics of the stabilized soil.关键词
