摘要
为解决高陡加筋土石坝体及边坡的稳定性问题,本文介绍了高韧聚酯有纺土工织物在广州市兴丰垃圾填埋场挡坝原位加高工程中的应用。研制了一种新型新旧坝体连接构造,可以有效地提高新坝与旧坝接触界面的抗滑移能力。经坝体监测,坝体水平位移速率满足规范要求,可供类似工程参考应用。
In order to solve the problem of the stability of high-steep reinforced earth-rock dams and slopes,this paper introduced the application of High-tenacity geotextile in the in-situ heightening project of the dam in Guangzhou Xingfeng Landfill.A new type of connection structure between new and old dams was developed,which could effectively improve the anti-slip capability of the interface between the new dam and the old dam.By monitoring by the dam body,it was found that the horizontal displacement rate of the dam body could meet the requirements of the specifications,which could be referenced by similar projects.
