Analyses of artificial freezing numerical simulation on pile well in soft layer
摘要
Abstract
The analyses of artificial freezing numerical simulation, based on the frozen temperature field theo-ry, the distribution of isotherm in freezing wall formation process and the freezing wall formed to meet the de-sign requirements of the time factor, are simulated and analyzed. Under certain assumptions by selecting spe-cific engineering geological parameters, focusing on under the combined action of four freezing pipes, frozen wall began to lap the time required to pay 56# pile in diameter around 80 cm formation. Frozen wall to meet the design requirements of 0. 55 m, the time required. The isothermal lines and the time when the frozen body being cross-circle, and the isothermal lines and the time when meeting the design requirements will be got.关键词
