摘要

对植被蒸腾作用以及阻滞地表径流作用进行了研究，提出生态护坡对边坡岩土体基质吸力的影响主要有3个方面：(1) 植被的蒸腾作用消耗边坡岩土体中的水分，使边坡体基质吸力升高，对边坡稳定有利；(2) 植被阻滞地表径流，增加降雨入渗量，使边坡体含水率增高，基质吸力降低，对边坡稳定不利；(3) 植被的存在究竟使边坡体基质吸力如何变化以及对边坡稳定是否有利，最终决定于降雨量和雨型。在此基础上，更进一步提出在降雨丰沛、暴雨较多的地区进行生态护坡时，应对边坡体采取防排水处理措施。

Abstract

The effects of vegetation transpiration and blocking surface runoff are researched; and three main influences of ecological slope protection on water content of slope rock-soil body and matric suction are put forward. The three aspects of influence are as follows: (1) The action of vegetation’s transpiration consumes the moisture of slope rock-soil body; and it recedes the water content of slope; increases the matric suction and benefits the stability of slope; (2) Vegetation blocks surface runoff and increases the rainfall infiltration

and it makes the water content increased

matric suction receded and disadvantage the stability of slope; (3) How the change of slope body water content and matric suction will benefit the stability of slope because of the existence of vegetation. All these decide by rainfall amount and rainfall type. Therefore

the slope must be made up into waterproof and drainage treatment for the ecological slope protection in area

with flush rainfall and torrential rain.
