Method and system of intelligent vibroflotation for deep overburden foundation
摘要
Abstract
China's southwest region is rich in hydraulic resources,but the development of hydropower engineering is restricted to engineering geological problems arising from the complex geological environment and deep overbur-den,such as anti-slide stability,permeability stability,uneven settlement deformation,erosion resistance,and earthquake liquefaction.Vibro stone columns is an effective means to improve the bearing capacity of the foundation and prevent liquefaction.This paper reveals the mechanism of"three-zone dynamic balance at the bottom,middle and top"and"three-domain interaction between machine,stone and soil"during the construction of vibro stone col-umns through experiments and numerical analysis.Relying on practical applications in the field,the paper puts for-ward the intelligent vibroflotation concept of full data acquisition during construction,real analysis of construction status,intelligent control during construction process,continuous optimization of construction parameters and online management of construction quality.Secondly,it proposes an intelligent vibroflotation control model based on state transition functions and real-time linkage control methods.It has developed an integrated digital collaborative work platform based on a"cloud-edge-end"intelligent vibroflotation work architecture and a complete set of intelligent vi-.broflotation equipment.It has established a digital evaluation system for the quality of crushed stone pile composite foundations.The study results have been applied to the treatment of thick overburden at the Hard Beam Pack Hydro-power Station.Post-monitoring shows good results,which can be used as a reference for similar projects.关键词
