摘要
对花岗岩风化物堆积坡的沉降调查测定表明 ,堆高 2 0～ 30m时 ,自然沉降休止期为 4～ 6年 ,沉降率达 1%～2 % ,30m高的堆积坡最大自然沉降量可达 6 0cm ,堆积坡上设置的浆砌石格栅护坡及排水沟等工程措施大都会因此而失效 ,只有植物措施能适应这种沉降变形。介绍了深圳市采取的“理顺水系、周边控制、植物固坡”
It is demonstrated from survey and investigation of granite weathering deposition slope sinking that the period of repose is 4 to 6 years and sinking ratio can reach 1% to 2% with pile height of 20 to 30 m, and the maximum natural sinking depth can be as much as 60 cm of deposition slopes. Therefore, grouted rubble fence, drainage channel and other treatments constructed on the slopes are easy to loss their effect, and only vegetative plants can stand the sinking deformation. The harness model of “smoothing water system, controlling surrounding, solidifying slope with vegetation and re plantation on top” adopted by Shenzhen city is introduced in the paper.
