Expansive soil side slope ecological protection structure and method considering fracture influence
The invention relates to the field of slope ecological protection, and particularly discloses an expansive soil slope ecological protection structure and method.The protection structure comprises a coarse sand layer, a geotechnical cloth layer, an improved matrix layer and a vegetation water-resisting layer which are sequentially arranged on a slope surface from bottom to top, and a drainage lattice is further laid on the slope surface; a capillary suction structure is arranged on the side wall of the drainage lattice, and a rigid support and a drainage ditch are arranged at the slope toe; the protection method comprises the steps of surface layer weathered expansive soil excavation, crack repairing, coarse sand layer and geotechnical cloth laying, improved matrix layer preparation and laying, vegetation water-resisting layer preparation and laying, drainage lattice laying and drainage ditch construction. According to the method, the influence of cracks and moisture change on the slope stability is considered, construction is convenient, ecological and environment-friendly effects are achieved, seepage-proofing and moisture-preserving regulation and control of slope body moisture can be effectively achieved, and the long-term stability of the expansive soil slope is guaranteed.
本申请涉及边坡生态防护领域，具体公开了一种考虑裂隙影响的膨胀土边坡生态防护结构及方法，其中防护结构包括在坡面由下至上依次设置的粗砂层、土工布层、改良基质层和植生隔水层，坡面还铺设有排水格构，排水格构的侧壁上设置有毛细抽吸结构，坡脚处设置刚性支护和排水沟；防护方法包括表层风化膨胀土挖除，裂隙修复，粗砂层和土工布铺设，改良基质层制备及铺设，植生隔水层制备及铺设，排水格构铺设和排水沟施工。本申请考虑了裂隙和水分变化对边坡稳定性的影响，施工方便，生态环保，能够有效实现对坡体水分的“防渗保湿”调控，保障膨胀土边坡的长期稳定性。
