摘要
在岩体裂隙网络二维稳定渗流数学模型的基础之上,引入温度对渗透系数的影响,进而影响渗流场中的水头分布.编写了相应程序计算渗流场中各节点水头值,最后通过工程算例进行了验证分析结果表明:温度高的区域渗透系数偏大,考虑温度对渗透系数影响,能更加准确的反映裂隙岩体中的水头分布状况,所得出的渗流场水头值和总渗流量比不考虑温度影响时的值偏高.
Based on the mathematic model of the 2D steady seepage field in fractured network rock mass,the effect of temperature on permeability coefficient is considered,and then the water head distribution in the seepage field is obtained.The corresponding program for calculating the water head values at all the nodes is compiled.An engineering case is presented for validating the water head distribution calculating program.It is shown that,the permeability coefficient in higher temperature area is greater than that in lower temperature area,to consider the effect of temperature on the permeability coefficient can more accurately reflect the water head distribution in the rock mass;the water head values considering the effect of temperature are generally higher than those no considering the effect of temperature.
