Geotechnical Analysis and 3D Fem Modeling of Ville San Pietro (Italy) Ville San Pietro(意大利)的岩土分析和三维有限元模拟
Abstract: The paper describes the three-dimensional numerical model of Ville San Pietro, an Italian village subject to slope movements causing damage. The church (dating back to 1776), which is the most significant building of the area, is modelled too. The information from geotechnical and geophysical surveys on field are used to define the model geometry and the soil properties. A finite element code is adopted to simulate the slope behavior in occurrence of water table fluctuations, detected by piezometers, and to evaluate the slope displacements and stability. The validation of the model is carried out using the inclinometer and interferometry measures and by on-site inspections. The model demonstrated a good ability to simulate the slope behavior during the raising and lowering of the water table. The critical areas computed by the numerical code are in good accordance to the actual portions affected by soil displacements and damages. The modelling presented in this paper is crucial for future analyses that will take advantage of an innovative monitoring system, which will be installed on site.

摘要:本文介绍了Ville San Pietro, 一个意大利村庄的三维数值模型,由于边坡运动导致边坡破坏。教堂(可追溯到1776年)是该地区最重要的建筑,在这项研究中也被建模。从岩土工程和地球物理勘测中获得的信息被用来定义模型的几何形状和土属性。采用有限元法模拟了由水位计检测到的水位波动时的边坡行为,评估了边坡的位移和稳定性。采用倾斜仪、干涉仪等测量手段和现场检查对模型进行了验证。该模型在模拟地下水位上升和下降过程中的边坡行为方面表现出了良好的能力。通过数值模拟计算出的临界区域与实际受土**移和破坏影响的部分有较好的一致性。本文提出的模型对今后的分析至关重要,它将用于安装一个新的监测系统。
