摘　　要：提出按照竖井井壁设计理论分析、设计人工挖孔桩护壁的思路,通过对比分析,得出计算表土层中人工挖孔桩护壁的侧压力更符合实际的公式,最后结合昆明新机场综合交通配套工程人工挖孔桩护壁实例对护壁强度进行核算,以合理确定护壁尺寸。The paper points out the ideas for analyzing and designing the wall protection of the manual hole digging pile according to the analysis of the theory for the vertical shaft walls, concludes the accounting formula to the facts of the side pressure of the wall protection of the manual hole digging pile by comparing and analyzing, and concludes the accounting of the strength of the wall protection combining with the example of the wall protection of the manual hole digging pile of the comprehensive traffic matching projects of the new airport in Kunming, so as to identify the sizes of the wall protection in a more reasonable way.

关 键 词：人工挖孔桩 护壁设计 护壁强度核算
