【摘要】：隨著環(huán)境問題的日益凸顯，同時(shí)具備工程防護(hù)和環(huán)境生態(tài)效應(yīng)特點(diǎn)的新型邊坡防護(hù)技術(shù)引起人們的廣泛關(guān)注。根據(jù)出現(xiàn)的這一問題，現(xiàn)在需要一種既可有效防治雨水沖刷，以及低成本、易施工，不影響植物的種植，，又具有維護(hù)周邊環(huán)境及生態(tài)平衡，而且能夠有效防止邊坡滑坡的新型技術(shù)。針對這個(gè)問題，本文著重研究兩種新型的土質(zhì)邊坡生態(tài)防護(hù)結(jié)構(gòu)： 本文采用試驗(yàn)方法確定木條式邊坡生態(tài)防護(hù)結(jié)構(gòu)的最佳布置。通過室內(nèi)抗沖刷模型的試驗(yàn)對比，得出采用本文所述的抗沖刷性木條生態(tài)防護(hù)邊坡較未采取任何防護(hù)形式的邊坡能更加有效地減小降雨對邊坡的沖刷。本文通過多組試驗(yàn)對比分析木條式生態(tài)防護(hù)結(jié)構(gòu)對邊坡雨水沖刷的影響，得出隨著木條出露高度的增高，木條式生態(tài)防護(hù)結(jié)構(gòu)的抗沖刷能力增強(qiáng)，隨著木條間間距的減小，木條式生態(tài)防護(hù)結(jié)構(gòu)的抗沖刷能力也在逐漸提高，但是增高的幅度呈減小趨勢。并且通過在現(xiàn)場施工中的具體運(yùn)用，進(jìn)一步驗(yàn)證了木條式邊坡防護(hù)的可操作性。 本文通過室內(nèi)模型試驗(yàn)，研究了一種短管式的邊坡生態(tài)防護(hù)結(jié)構(gòu)，通過對多種管徑的實(shí)驗(yàn)對比，采用管徑為10cm、15cm、20cm的短管式邊坡防護(hù)結(jié)構(gòu)的邊坡模型比未采用防護(hù)措施的在60min內(nèi)總沖刷量分別降低了75.5%，68.2%、52.9%。從而得出結(jié)論：隨管徑減小邊坡的抗沖刷能力明顯增大，但是增大的幅度呈減小趨勢。由防沖刷能力和經(jīng)濟(jì)效應(yīng)綜合考慮，得出了一個(gè)管徑的最優(yōu)值。 本文對木條式邊坡生態(tài)防護(hù)結(jié)構(gòu)和短管式生態(tài)防護(hù)結(jié)構(gòu)在徑流作用下進(jìn)行了對比，得出結(jié)論：采用木條式邊坡防護(hù)結(jié)構(gòu)和短管式邊坡防護(hù)結(jié)構(gòu)的邊坡模型比未采用防護(hù)措施的單位時(shí)間沖刷量降低最大為38.9%和56.7%。
[Abstract]:With the increasingly prominent environmental problems, the new slope protection technology with the characteristics of engineering protection and environmental ecological effects has attracted wide attention. Based on this emerging problem, there is now a need for a system that can effectively prevent and control Rain Water scour, as well as low cost, easy construction, without affecting plant cultivation, and has the ability to maintain the surrounding environment and ecological balance. And can effectively prevent slope landslide of the new technology. In view of this problem, this paper focuses on two new types of soil slope ecological protection structure: In this paper, the optimum arrangement of ecological protection structure of wooden slope is determined by test method. Through the comparison of indoor anti-scour model, it is concluded that the slope with the ecological protection of the anti-scour wood strip mentioned in this paper can reduce the erosion of the slope more effectively than the slope without any form of protection. In this paper, the effects of wood strip ecological protection structure on slope Rain Water scour are compared and analyzed through many experiments. It is concluded that with the increase of the height of wood strip exposure, the anti-scour ability of wood strip ecological protection structure increases, and with the decrease of the space between wood strips, the anti-erosion ability of the wood strip ecological protection structure increases with the increase of the height of the wood strip. The scour resistance ability of wood strip ecological protection structure is also increasing, but the increasing range is decreasing. And through the concrete application in the field construction, it further verifies the operability of the wooden slope protection. In this paper, a short-pipe slope ecological protection structure is studied through indoor model test. The total scour of the short pipe slope with the diameter of 10 cm ~ (15) cm ~ (20) cm is reduced by 75.5% ~ 68.2% and 52.9%, respectively, compared with that of the one without protection measures in 60min. It is concluded that the anti-scour ability of slope increases obviously with the decrease of pipe diameter, but the increasing amplitude shows a decreasing trend. Considering the scour resistance and economic effect, the optimum value of pipe diameter is obtained. This paper compares the ecological protection structure of wooden slope with that of short pipe slope under the action of runoff. It is concluded that the slope model with wooden strip slope protection structure and short pipe slope protection structure can reduce the scour amount per unit time by 38.9% and 56.7% respectively.
