摘要: PVD插板在软土地基中形成竖向的排水通道。在上部辅加荷载的作用下,水从上部铺设的沙垫层形成水平排水通道排出。使软土地基在较短的时间内达到较高的固结度。在缅甸成品油库项目中,利用PVD排水板排水法在较短的时间内达到理论沉降计算,加速了地基固结沉降速度,大大缩短了施工工期。
Abstract: The PVD drainage board formed a vertical drainage channel in the soft soil foundation. Under the pressure of the upper auxiliary load, water was discharged from the horizontal drainage channel formed on the upper sand cushion layer. The soft soil foundation is promoted to achieve a higher degree of consolidation in a shorter period. In the Myanmar product oil depot project, the PVD drainage board is used. The theoretical settlement calculation is achieved in a short period of time, which accelerates the consolidation settlement speed of the foundation and greatly shortens the construction period.
