摘要
进行冻结壁厚度设计时，通常采用永久地压值作为外荷载，往往导致设计的冻结壁厚度不足．本文通过粘土冻胀的成因分析，得出需用原始冻胀力这一被动地压值作为设计冻结壁厚度外荷载的结论，并用理论推导的方法得出原始冻胀力的求算公式．
To design a frozen shaft wall,the permanent earth pressure was usually taken as an external load. But,in this way,the thickness of frozen wall was often inadequate. By way of analyzing the genesis of clay heaving,a conclusion is drawn that it is necessary for thickness designing of frozen shaft wall to take the primary heave pressure or a passive earth pressure as the external load. Also, a formula calculating the primary heave is derived theoretically.
