深圳市属滨海城市,主山脉走向基本为EW向,由北向南由低山丘岭逐渐到滨海平原。地层岩性软硬分布不均,构造破碎,年降雨量大,地下水丰沛。深圳市边坡病害的类型有地表松散层中的边坡滑坡和坍塌、软变质岩中沿顺坡向断层的滑动、混合岩中沿顺坡向断层的滑动和花岗岩中构造硬核的失稳。边坡病害的产生有以下规律:(1)地表水和地下水的共同作用产生的多;(2)EW向山脊的南侧发生的病害多;(3)软岩中的滑坡、坍塌多,硬岩中崩塌、落石多,破碎岩体中坍塌和滑坡较多;(4)深圳大断裂对边坡病害的影响大,其上盘边坡病害多,下盘少;NE向主断裂带和其他向断裂带交叉处的边坡病害多。尽管在边坡病害的防治中采用大量工程以及新技术,但今后深圳市边坡病害防治应向以下几个方向发展:贯彻“地质是基础”的原则、探索新技术、加强监测、加强防治工程效果评价的研究以及制定边坡病害防治标准。
Shenzhen is a coastal city, the main mountain to EW direction, from north to south gradually from the low hills to the coastal plains. Stratigraphic lithology is not uniform distribution of hard and soft, structural crushing, annual rainfall, abundant groundwater. Slope types in Shenzhen include slope landslides and collapses in loosely surfaced strata, slip along fault-prone faults in soft metamorphic rocks, slip along fault-prone faults in mixed rocks and instability of hard nuclei in granites . Slope disease has the following rules: (1) the combined effect of surface water and groundwater is much; (2) there are many diseases on the south side of EW ridge; (3) the landslides in soft rock are collapsed and hard There are many rockfalls and rockfalls, and there are more collapses and landslides in the crushed rock mass. (4) The large faults in Shenzhen have a great influence on the slope diseases. Slope to the fault zone more disease. Although a large number of engineering and new technologies are used in the prevention and treatment of slope diseases, the prevention and control of slope diseases in Shenzhen should be developed in the following directions in the future: To implement the principle of “geology is the foundation”, explore new technologies, strengthen monitoring and strengthen prevention and treatment projects The evaluation of the effect and the development of slope disease prevention and control standards.
