摘要
本文基于弹性理论，给出在半无限弹性体钻一长圆柱孔后的应力状态，考虑了孔壁收缩膜和土粘聚力对孔壁的影响，得出稳定计算公式。同时，文中分析了孔周地面堆载对孔壁稳定性的影响和临近基础钻孔对建筑物的影响。文中还就两项工程的钻孔缩颈资料进行了分析。
A calculating formula
for stability is given herein acquired from the stress state of semi infinite elastic body after a
columnar hole is drilled,considering the effects of shrinkage membrance of wall and cohesive
force of soil on borehole wall.The influence of stocking upon ground surrounding the borehole on
the stability of hole wall and the influence of nearby foundation drilling on the building are also
analyzed.Empirical formula for shirinkage throat of borehole is also provided based on the
analyses of data of tow projects.
