Research on the measurement of static friction force of bamboo root soil

Abstract

Root soil maximum static friction play as an important parameter to measure the effect of soil reinforcement.Accurate measurement of it has the higher application value and research significance. this paper takes the bamboo root bamboo developed as the researching object ,and uses a self-made device to simulate the condition of natural soil ,adopts the tension gauge measurement method to implement experiments. These experiments measure following factors: the maximum static friction of bamboo root - soil under the factors of the self weight stress, water content , depth, root depth, root diameter of different soil. Analyzes the impact of the above on root soil interface friction. The results show that: the maximum static friction of bamboo root - soil interface becomes higher with the increasing of soil depth and root depth. The relationship between maximum static friction and root diameter, soil depth is approximately power function .Under the same soil depth, In contrast to 32.7% moisture content of the soil, the maximum static friction of bamboo root - soil is greater when the moisture content of the soil is 23.5%
