摘要
针对风积沙的特点,通过对不同施工方案的比较与分析,介绍了水平旋喷桩和三台阶临时仰拱法在风积沙隧道施工中的应用,实践表明三台阶临时仰拱法具有很多优点,值得推广。
According to the characteristics of aeolian sand and the comparison and the analysis of the dif-ferent construction schemes, this paper introduces the application of the horizontal rotary jet grouting pile and the three steps temporary inverted arch method in the construction of aeolian sand tunnel. Practice shows that the three steps temporary inverted arch method has many advantages and is worth promoting.
