摘要
针对浅表层吹填土的真空预压技术,从模型试验的角度针对排水板的不同布置形式进行了试验研究。通过模型试验与土体表面沉降、真空度测量,认为真空度随排水板沿深度的消散和在土体内部传递的消散不可忽略,在这些区域中,驱动土体固结发展的可能不是真空度的传递,而是土中水的缓慢渗流。最大排水距离应该是衡量不同排水板布置效果的关键数据。
For the vacuum preloading technology of shallow surface dredger fill,from the perspective of simulation model test,different arrangement forms of drainage board were studied. Through the implementation of model test and the measurement of soil surface subsidence and vacuum degree,it was argued that the vacuum degree dissipation along with drainage board in depth and soil internal transfer cannot be ignored in fact. In these area,soil consolidation development may not be caused by the vacuum degree transfer,but the slow seepage of soil water. However,the maximum drainage distance should be the key data to measure the effect of different drainage board arrangement.
