红当公路盐渍土病害治理的初步探索

Probe into the Remedy of the Salty Soil Hazard in Hongdang Road

本文根据毛细管水上升高度,提出了不同粒径的盐清土毛细管水最大高度的计算公式及设计隔离层的计算方法;在对盐渍土的物理、力学及水理方面试验的基础上,找到了盐胀规律及变化机理;掌握了盐渍土的冻结条件,解决了易溶盐对道路工程的破坏问题。文中还报道了试验的治理结果。

In this paper, the formulae for the maximun height of capillary water in the saline soil with various grain sizes as well as the procedure for insulation course design are proposed. Based on the tests of the physical and mechanical properties of the salty soil and its hydroscience, the mechanism of salty expansion is developed and the conditions of the saline soil freezing are analyzed to help alleviate the damage of highway caused by soluble salts. The results from the experimental road are also presented.
