人工挖孔灌注桩的孔壁稳定性
STABILITY OF HOLE-WALL IN MANUALLY-EXCAVATED HOLE PILES
【摘要】 人工挖孔桩在挖孔后,孔壁周围土体将会产生应力集中。利用弹性理论,推导了孔壁周围土体的应力计算公式,并用莫尔—库仑极限平衡准则对孔壁稳定性进行判别。
【Abstract】 After construction of manually-excavated hole piles have been finished, the stress concentration in periphery soil of hole-wall will be produced. Based on elastic theory, the stress calculation formula for the periphery soil of hole-wall can be deduced, and hole-wall stability will also be determined by the Mohr-Coulomb Criterion.
