水泥砂浆生态护坡模拟冲刷试验

Simulation washout experiment for ecological slope protection by cement mortar

为了验证一种新型水泥砂浆生态护坡结构的防护效果,采用室内模拟试验的方法,分析了该种水泥砂浆生态护坡的抗雨水冲刷能力,提出了水泥砂浆防护形式的设计参数,并进行水泥砂浆防护不同构造的对比试验研究。试验结果表明:该种防护技术下,泥沙冲刷量至少比裸坡少了60%,防止水土流失效果明显,其中采用间距20cm突起构造的形式对于坡面的防护效果是最经济适用的。

In order to validate the mortar protective effect of ecological slope protection structure of a new type of cement,the indoor simulation test method was adopted,the ability to resist the rains washed out of ecological slope protection of this kind of cement mortar was analyzed,the cement mortar protection forms of design parameters are put forward,and different tectonic contrast of the cement mortar protection is experimen-tally studied.Theoretical analysis and experimental results show that this kind of pro-tection technique under sediment erosion quantity is at least 60% than those in bare slope,the prevention of soil erosion effect is obvious,which takes the form of spacing between 20 cm swelled structure for the slope surface protection and this is the most af-fordable.
