MEASUREMENT AND NUMERICAL ANALYSIS OF FREEZING PRESSURE OF THE FREEZING WALL IN THE THICK CLAY STRATA

摘要: 为了研究深厚黏土层冻结壁冻结压力的变化特征,根据现场实测结果获得冻结压力随温度变化的发展趋势. 结合对现场实测数据的分析和ADINA 有限元法的数值模型,能够很好地模拟人工冻结地层应力场的变化规律,为工程实践提供参考.

Abstract: This paper studies the variations of the freezing pressure of the freezing walls in the thick clay strata, against the temperature change by the field measured results. Combining the analysis of actual measured data with the numerical model of the ADINA FEM method, the artificial freezing stress field is simulated to provide a reference for the engineering practice.
