Abstract
Description
Technical Field
[0001] The present invention relates to the field of analysis of thick soft soil, and in particular to an extended-range vacuum preloading analysis method and system for thick soft soil. Background Art
[0002] In the prior art, the vacuum preloading method is to use a vacuum pump, a sealing system, and a drainage board to extract the moisture in the foundation. As the vacuum degree gradually extends in the depth direction in the drainage channel and diffuses to the surrounding soil, the pore water in the soil is continuously discharged, and the soil is finally consolidated and compacted. During construction, the existing vacuum preloading method is to first lay a sand cushion layer on the surface of the soft soil foundation that needs to be reinforced, then insert a drainage board, and then use an airtight sealing membrane to isolate it from the atmosphere. A vacuum pump or other vacuum means is used to evacuate the surface to form a negative pressure under the membrane and transmit it from the shallow layer of the foundation to the deep layer, thereby increasing the effective stress of the foundation. However, during use, this construction method often has the problem of the vacuum degree gradually attenuating in the drainage board, which makes it difficult for vacuum preloading to handle deeper soft soil. For this reason, the prior art proposes an extended-range vacuum preloading method to further handle deeper soft soil, but the prior art cannot effectively analyze the extended-range vacuum preloading method. If conventional empirical analysis methods are used, the error is large. Therefore, there is an urgent need for an extended-range vacuum preloading analysis method for deep soft soil to analyze and clarify the problem of vacuum degree attenuation in the extended-range vacuum preloading method and ensure effective treatment of deeper soft soil.
