Deep soft soil roadbed composite structure and construction method
The embodiment of the invention provides a deep soft soil roadbed composite structure and a building method. The roadbed structure sequentially comprises a first soft soil layer, a second soft soil layer, geotechnical cloth, a broken stone cushion layer, a block stone layer, a gravel cushion layer, a cement stabilized broken stone layer, a cement mortar bonding layer and a surface layer composite material plate from bottom to top. In addition, the roadbed composite structure further comprises drainage blind ditches, water collecting wells, drainage plates, micro piles and drainage ditches. The roadbed structure comprehensively adopts principles and technologies of dynamic consolidation drainage, rigid support and a flexible surface layer, and dynamic consolidation drainage comprises a vertical drainage system and a horizontal drainage system. The rigid supporting effect of the micro piles can improve the bearing capacity of soft soil and reduce the deformation of an upper-layer structure of a roadbed. The surface layer composite material plate has good toughness and strength, and the service life of the surface layer is prolonged. The bearing capacity and stability of the soft soil roadbed structure can be effectively improved, and important technical support is provided for soft soil area roadbed design, building, management and maintenance and the like.
本申请实施例提供了一种深厚软土路基复合结构及修筑方法。所述路基结构从下往上依次为第一软土层、第二软土层、土工布、碎石垫层、块石层、砂石垫层、水泥稳定碎石层、水泥砂浆粘结层、面层复合材料板。此外，还包括排水盲沟、集水井、排水板、微型桩以及排水沟。所述路基结构综合采用动力固结排水、刚性支撑以及柔性面层的原理与技术，动力固结排水包括竖向排水和水平排水体系。微型桩的刚性支撑作用，可提高软土的承载力，降低路基上层结构变形。面层复合材料板具有很好的韧性和强度，提高面层使用寿命。本发明可有效地提高软土路基结构的承载力和稳定性，为软土地区路基设计、修筑及管养等提供重要技术支撑。
