| description | In order to reinforce the soft sludge and makes it meet the certain bearing capacity of the engineering construction, the consolidation and solidification composite technology is used to reinforce the sludge in the field site. During the test, a certain thickness of sludge is divided into a shallow solidification layer and a deep consolidation layer. The solidification technology is used to reinforce the shallow (≤1 m) sludge so as to form a high-strength overlying crust. For the deep (>1 m) sludge, the vacuum preloading technology is used to improve the bearing capacity of the deep sludge and control the later settlement of the reinforced soil. The experimental results show that the characteristic value of the shallow solidified soil bearing capacity ranges from 109 to 330 kPa when the dosage of solidified agent is 0.6%～5.0%. The consolidation and solidification composite technology has a prominent effect on the reinforcement of the sludge and the characteristic value of the overall bearing capacity of the layered reinforced soil varies between 89 and 230 kPa. After the solidification treatment of the shallow sludge, the soil strength is higher, which can generate an obvious diffusion effect on the surface load and effectively reduces the additional stress in the underlying layer caused by the surface load. The stress diffusion angle of shallow solidified soil in most test units varies between 19.474° and 26.303° in this experiment. |
