More Information
Summary:The invention discloses a drainage-reinforcement structure for improving the stability of a soft clay heap and a construction method. The drainage-reinforcement structure and a soft clay layer of the soft clay heap are stacked in sequence, and an inclination angle is formed between the drainage-reinforcement structure and the horizontal plane where the soft clay layer of the soft clay heap is located in the slope direction; the drainage-reinforcement structure comprises a drainage layer and a tensile permeable layer, the tensile permeable layer is arranged in the drainage layer, and a drainage ditch is formed in one side of the drainage layer. According to the drainage-reinforcement structure, the friction strength of a rib-soil interface can be enhanced, the shear strength of the soft clay is improved, the internal stress distribution of a soft clay heap is more uniform, the differential settlement of the soft clay heap is reduced, and the overall stability of the soft clay heap is further obviously improved
