Based on the analysis of the mechanism of water conservation for soil-root composite (SRC), a new concept, anti-water erosion strength is proposed, which can be defined as the maximum stress of the micro-filter that can resist to the surface runoff. The relationship between the anti-water erosion strength and the amount of roots is derived. According to the modelling tests, the direct shear strength can be describledby Coulomb equation, i. e, τf=σtan+C, where is the angle of the internal friction between soil...

Based on the analysis of the mechanism of water conservation for soil-root composite (SRC), a new concept, anti-water erosion strength is proposed, which can be defined as the maximum stress of the micro-filter that can resist to the surface runoff. The relationship between the anti-water erosion strength and the amount of roots is derived. According to the modelling tests, the direct shear strength can be describledby Coulomb equation, i. e, τf=σtan+C, where is the angle of the internal friction between soil particles, soil and roots; C is the sum of the soil, soil-root cohesion and the roots anchorage stress. The value of and C is in the range of 13°~25° and 16~60 kPa respectively. It is found that the shear strength of SRC increasing with the amount increasing of the roots, but decreasing with the increasing in moisture content.The value of C is directly portional to the amount of roots. However, value of seems independent to roots.

分析了草本植被根系保持水土效能的机理,提出将根茎连接处形成的微型“栏上栅”及“滤水土体”抵抗径流推移破坏的极限能力,作为土壤-草本植被根系复合体的抗水蚀强度,并研究了它与含根量的相关性。通过复合体原型结构试样的直剪试验,证明复合体的抗剪强度τf与法向压力σ的关系符合库伦定律,即τf=σtan+C,但式中是土粒与土粒、土粒与根系之间的综合内摩擦角(13°~25°);C是土位与土粒、土粒与报系之间的凝聚力,以及由土的剪应力传递给根系而引起的根系抗拔力之和(16~60kPa)。由试验结果知,复合体抗剪强度随含根量增加而增大,随含水量增多而减小;C值与含根量呈正相关,而值与含根量关系不大。

The modulus of infiltration (MOI),modulus of runoff(MOR) and modulusof sediment (MOS) are introduced as the index for evaluating the anti-water erosion ability of the soil-root composite(SRC). The relationship of MOI, MOR and MOS with the ground slope, rainfall intensity, seepage coefficient and anti-water erosion strength of SRC are found out through the rainfall simulation experiment, which provides thescientific basis for evaluating the soil-water conservation efficiency.

Applying the basic theory of engineering mechanics and experimental method of soil mechanics, the effect of grass roots on shear strength was measured. According to the model tests, the direct shear strength of SRC can be described by Coulomb equation. The shear strength of SRC increased with the amount of roots. Presuming that the action of roots in soil is similar that of steel bars in concrete, and proposed using the formula for reinforced concrete to calculate the relations formula of SRC shear strength and the amount of root i.e. τ=τ o+0.14 M r f r. The formula showed that the friction force and anchorage stress can prevent the soil from being sheared. The roots can raise the strength of the soil, and contribute to support and advance of the machine.
