Airport high slope area geotextile material layered laying combined strengthening method
The invention belongs to the technical field of high slope area geotextile material layered laying in airport constructional engineering, and provides an airport high slope area geotextile material layered laying combined strengthening method to solve the problem of restrictions faced by high slope airport stability, particularly the high slope airport stability in southwest regions. Foundation treatment is conducted on a slope area existing foundation through SDDC gravel piles; a riding track platform is arranged in the slope area in the vertical height at intervals, and a back pressure platform with the width being 10 m is arranged on the toe of a slope; five layers of geotextile materials are laid on the inner side of a riding track in a filling body, the two upper layers and the two lower layers are geogrids, woven geotechnical cloth is adopted as the middle layer, and two layers of rectangular three-dimensional water drainage plates are laid on the riding track platform upwards by1 m to 2 m; and stone filling and vibration rolling are adopted. The timely water drainage effect of the three-dimensional water drainage plates and the slope protection effect of the geogrids are effectively brought into play, underground water in the slope area is rapidly drained, capillary water is blocked under the high load, the isolation effect and the foundation strengthening effect are achieved at the same time, and overall stability of the high fill slope is ensured.
本发明属机场建筑工程中高边坡区域土工材料分层铺设技术领域，为解决高边坡机场稳定性面临的制约，尤其西南地区高边坡机场稳定性问题，提供一种机场高边坡区域土工材料分层铺设组合加固方法。边坡区域原地基采用SDDC碎石桩进行地基处理；边坡区域垂直高度间隔设置一马道平台，坡脚设置10米宽的反压平台；在填筑体中马道内侧铺设五层土工材料，上两层和下两层均为土工格栅，中间一层采用有纺土工布，马道平台往上1‑2米铺设两层矩形三维排水板；采用石料填筑，振动碾压。有效发挥三维排水板及时排水和土工格栅防护边坡作用，迅速地排出边坡区域内的地下水，在高荷载下阻断毛细水，同时起到隔离和地基加固作用，保证高填方边坡的整体稳定。
