【摘要】 基于半解析法研究了超固结饱和土的一维固结问题,采用Fortran语言编制相应的计算程序ODLCAOS,并利用该程序对超固结饱和土的一维固结性状进行了分析。研究表明,与传统的Terzaghi固结理论所描述的不同,超固结饱和土的超静孔压消散速率与沉降发展速率并不一致,荷载和先期固结压力的大小均对固结速率有明显影响。更多还原

【Abstract】 The problem of one-dimensional consolidation of over-consolidated saturated soil is studied based on semi-analytical method. The relevant computer code ODLCAOS is developed by Fortran programming. By using this program, the one-dimensional consolidation behavior of over-consolidated soil is investigated. It is shown that, unlike this described by traditional Terzaghi’s consolidated theory, the rate of excess pore water pressure dissipating is different from that of settlement developing, and both the magnitude of load and that of pre-consolidated pressure have significant influence on the rate of consolidation.更多还原
