| 摘 要： | 从冻胀对基坑工程的不利影响着手进行分析,并以北京某越冬土钉墙支护工程为例,分析了冻胀力对该类支护形式稳定性的影响,结果表明,由冻胀引起的水平位移主要发生在冻胀土,而弱冻胀土较小;冻胀引起的土钉拉力变化值在冻胀土中较大,而非冻胀土中值较小。

| Abstract: | The paper analyzes the harmful influence of the freezing heave on the foundation pit projects,analyzes the influence of the freezing heave force on the stability of the kind of support form by taking some soil nailing wall support project in winter construction of Beijing,and proves the horizontal displacement caused by the freezing heave mainly occur on freezing heave soil and the displacement on the weak freezing heave soil is little,and the change value of the tension on the freezed soil is big while the change value on the non-freezed soil is little. |

| Keywords: | freezing heave soil nailing wall horizontal displacement tension of soil nailing support of foundation pit |
