Title : Experimental Investigation on Flow Velocity Distribution in Mountain Rivers with Coarse Sediment Bed
ZHANG Shaopei, , YANG Yang, , YANG Fengguang, , WANG Xiekang, , LIU Xingnian,
Abstract : In mountain rivers with coarse sediments, the ratio of water depth to sediment diameter (h/d) is relatively small especially under the condition of shallow water depth. Therefore, the vertical velocity distribution along the river cannot be described accurately with traditional logarithmic or logarithmic-wake law. In this paper, flume experiments were carried out with two kinds of sediments (glass beads d=1.4 cm and pinpong d=4 cm) to test the influence of coarse sediment on vertical velocity di

Title : Model Test of Salt-frost Heaving Limit Depth of Coarse-grained Sulphate Saline Soil
YANG Peng, , CAO Yapeng, , ZHU Yanpeng, , WANG Buxiang,
Abstract : In order to perfect the salt expansion theory of coarse-grained saline soil and explore the influencing factors and mechanism of the salt−frost heaving force, 96 groups of coarse-grained sulphate saline soil samples are prepared artificially then indoor model tests have been carried out by self-designed test device. Test results showed that the sensitive range of temperature on the salt−frost heaving force is −0.2??−1.0?. The salt content had no influence on the rules tha
