| 摘 要： | 研究目的:目前在土坡工程防护设计中,植被防护土坡一般还仅局限于园林工程师的活动范畴。然而,在提倡环境保护的今天,利用根系发达的植被,把园林工艺学和土力学与环境岩土工程技术结合到一起应用到实践中去,可以很好地实现硬化和绿化的和谐统一。为此开展植被护坡的根系固土实验研究,借鉴纤维加筋土的研究思路,研究1 mm粗和1～2 cm长的根系纤维,在不同根系拌合长度和拌合量时对根系复合土强度和变形的影响。研究结论:实验表明根系能够提高土体的粘聚力c,但一般不改变土体的内摩擦角φ,类似于加筋土的试验发现;根系对土体延展性有一定的改善作用,多年生植被长的根系更加有利于边坡防护。

| Abstract: | Research purposes: In the slope protection design and construction,the vegetative protection slopes is still considered as the routine activities of the landscape engineers.However,if some plants with strong and long root system are used for the slope stabilization along with the soil mechanics and the technology of the environmental geotechnical engineering,the good coordination between land hardening and land green can be realized.So it is necessary to do the experimental research on the root system of th... |
