摘要
基于超固结饱和土固结理论,针对变荷载、自重应力分布等条件下提出了相应的一维超固结土问题的控制方程,总结出六个超固结土的一维线性固结计算参数。鉴于国内通用的固结渗透试验设备的种种弊端,提出利用GDS高级固结仪对萧山黏土进行一维固结和渗透联合试验,根据对试验数据的整理分析,确定了基于GDS高级固结仪系统的超固结土的一维固结计算参数,为验证超固结土理论奠定基础。
Based on the available theories for over-consolidated soil, the equations for one-dimensional linear consolidation of soft soil under time-dependent loading considering the effect of stress history and actual overburden pressure are proposed. Then six computational parameters on one-dimensional over-consolidated soil are summarized. For the shortcomings of traditional testing equipment and method, GDS system is developed to investigate the consolidation behavior of Xiaoshan Clay, and the computational parameters for one-dimensional over-consolidation are listed in detail.
