Abstract Adjacent building damages induced by excavations is crucial for excavations in urban areas. Excavation induced damage involved complex soil-structure interactions and complicated ground movements which should be evaluated at the depth of foundation of adjacent buildings. Empirical or semi-empirical methods for evaluation of ground movements induced by excavations have not been well-established because the observed ground movements are very limited. The objective of this study is to establish a simplified assessment for building damage potential based on subsurface ground movements caused by excavations. A series of parametric study by numerical analyses with an advanced soil model was carried out. A set of simplified equations for predicting the profiles for both subsurface ground settlements and lateral ground movements were proposed. Three assessment models with or without considering structural stiffness and subsurface ground movements were employed in estimating the damage potential index (DPI) for two case histories. The models were proved to yield a more reasonable assessment result for building DPI based on the proposed simplified expression of subsurface ground movements.

用于相邻建筑物潜在损坏评估的挖掘引起的地面运动的简化估计

摘要 开挖引起的相邻建筑物损坏对于城市地区的开挖至关重要。开挖引起的损坏涉及复杂的土壤-结构相互作用和复杂的地面运动，应在相邻建筑物的基础深度进行评估。由于观测到的地面运动非常有限，用于评估由开挖引起的地面运动的经验或半经验方法尚未完善。本研究的目的是建立一个基于挖掘引起的地下地面运动的建筑物损坏可能性的简化评估。使用先进的土壤模型通过数值分析进行了一系列参数研究。提出了一组用于预测地下地面沉降和横向地面运动剖面的简化方程。使用或不考虑结构刚度和地下地面运动的三个评估模型来估计两个案例历史的潜在损坏指数 (DPI)。事实证明，基于拟议的地下地面运动的简化表达式，这些模型为构建 DPI 产生了更合理的评估结果。
