Carbonaceous soft rock-geosynthetic material composite roadbed structure
The embodiment of the invention provides a carbonaceous soft rock-geosynthetic material composite roadbed structure. The carbonaceous soft rock-geosynthetic material composite roadbed structure comprises a bottom isolation layer, geosynthetic material reinforcing and edge covering seepage-proofing areas, a carbonaceous soft rock core filling area and a roadbed; the bottom isolation layer is located above the foundation and is used for preventing water from migrating to the carbonaceous soft rock core filling area due to rising of the underground water level or the capillary water effect; the carbonaceous soft rock core filling area is positioned above the bottom isolation layer; the roadbed is positioned above the carbonaceous soft rock core filling area; the geosynthetic material reinforcing and edge covering seepage-proofing areas are located on side slopes on the two sides of the roadbed, the two sides of the carbonaceous soft rock core filling areas are reversely covered with a geosynthetic material, and the geosynthetic material reinforcing and edge covering seepage-proofing areas are used for preventing rainfall and side slope runoff from seeping into the carbonaceous soft rock core filling area through the side slopes on the two sides. The carbonaceous soft rock-geosynthetic material composite roadbed can form a closed waterproof or water-blocking system, external wateris prevented from infiltrating the carbonaceous soft rock core filling area, the humidity state of the carbonaceous soft rock core filling area is stable, and long-term performance stability of the carbonaceous soft rock roadbed is guaranteed.
本发明实施例提供了一种炭质软岩‑土工合成材料复合路基结构，包括：底部隔离层、土工合成材料加筋与包边防渗区、炭质软岩填芯区和路床；底部隔离层位于地基上方，用于防止地下水位上升或毛细水作用引起的水分向炭质软岩填芯区迁移；炭质软岩填芯区位于底部隔离层上方；路床位于炭质软岩填芯区上方；土工合成材料加筋与包边防渗区位于路基两侧边坡，采用土工合成材料将炭质软岩填芯区的两侧反包其内，用于阻止降雨和边坡径流通过两侧边坡入渗炭质软岩填芯区。本发明炭质软岩‑土工合成材料复合路基可形成封闭的隔水或阻水系统，避免外界水分入渗炭质软岩填芯区，使得炭质软岩填芯区湿度状态稳定，保障炭质软岩路基长期性能稳定。
