煤系土边(滑)坡工程案例在郴州地区最为常见,煤系土具有岩层软硬不均、层间胶结较差、结构松散、开挖后风化速度较快且遇水易软化、性能极不稳定和结构易破坏而丧失强度等特点。以郴州市骆仙岭骆仙西路北侧C区典型煤系地层边(滑)坡治理工程案例为研究背景,对其滑动失稳变化全过程进行分析研究,通过有限元FLAC3D三维数值模拟等手段,研究不同施工时序与过程稳定性控制之间的内在联系。并针对性采取应急抢险治理措施,治理后滑坡恶化趋势得到有效控制,达到预期安全性要求。
Coal-bounding soil (slippery slope) engineering case is the most common in Chenzhou area. Coal-bearing soil has the features of soft and hard rock formation, poor cementation between layers, loose structure, fast weathering after excavation, water softening, Instability and easy to destroy the structure and loss of strength and so on. Based on the case study of the typical coal strata edge (slippery slope) treatment project in the area C of Luo Xian West Road, Luo Xian Ling, Chenzhou, the whole process of the sliding instability change is analyzed and studied. By means of finite element FLAC3D 3D numerical simulation and other means, The Relationship Between Construction Timing and Process Stability Control. And targeted emergency rescue measures, the trend of landslide deterioration after the effective control, to achieve the expected safety requirements.
