“卸荷拱”理论在地下人防工程稳定分析的应用

Application of Relieving Arch Theory to Stability Analysis of Air Defense Engineering

通过对三门峡市区地下人防工程的分布及规模进行调查分析,在取得可靠参数的情况下,经过"卸荷拱"理论严格计算、分析,确定地下人防工程处于稳定状态。决定采用预钻孔灰土挤密桩处理湿陷性黄土地基,基础形式为扩展基础,2年来的运行状况良好。

Through research to the distribution and scale of Sanxiamen air defense shelters, reliable parameter is obtained; then the calculation and analysis ＂with Relieving Arch Theory say that the air defense shelters stay in a stable state. Treatment of the collapsible loess with prebored lime-soil compaction pile with a extended foundation has proved to operate well in the past two years.
