Abstract

Purpose. The aim of the research is mathematical analysis and forecasting of dispersive soils behaviour based on the study of inclinometric observations data in the area of the natural-technical system of the Dnister PSPP. Methodology. The research methodology is based on mathematical analysis and modelling of processes occurring in the mountain massif on which the Dnister PSPP is located, using the finite element method. Results. The paper presents an analysis of the results of geotechnical monitoring of the behaviour of dispersive soils, implemented on the basis of inclinometric measurements on the territory of the Dnister PSPP. Quantitative parameters of horizontal displacement distribution in inclinometric wells are established. They made it possible to detect negative dynamics in the geological horizons N1-2ap and N1p+v, which is apparently caused by technogenic load caused by the Dnister upper reservoir. The behaviour of dispersive soils under the influence of natural and technogenic loads has been modelled. Based on the simulation results, the change of the sign of deformations under the influence of additional load, which can be the filling of the Dnister upper reservoir, is confirmed. Obviously, the use of this method alone does not allow full detecting and tracking modern geological, seismic and geodynamic processes. A combination and detailed analysis of different monitoring methods (geophysical, geodetic, parametric, vibrometric, hydrogeological, temperature, visual-instrumental and others), as well as modelling the behaviour of the object under the influence of natural and technogenic factors is optimal. Such simulations could be used in the design of other objects of this type, so this is a promising area for further research. Originality. For the first time, a mathematical analysis and forecasting of the behaviour of dispersed soils in the area of the natural and technical system of the Dnister PSPP was conducted on the basis of studying the data of inclinometric observations. Practical significance. The proposed technique can be used in the design of other objects of this type, as modelling the behaviour of the object under the influence of natural and technogenic factors makes it possible to assess possible risks and prevent them.

意图本研究的目的是在研究Dnister PSPP自然技术系统区域的测斜观测数据的基础上,对分散性土壤行为进行数学分析和预测。方法论该研究方法基于对Dnister PSPP所在山体中发生的过程的数学分析和建模,并使用有限元方法。后果本文分析了在Dnister PSPP地区进行的基于测斜测量的分散土特性岩土工程监测结果。建立了测斜井中水平位移分布的定量参数。他们使得在地质层N1-2ap和N1p+v中检测到负动力学成为可能,这显然是由Dnister上部储层引起的技术成因载荷引起的。对分散性土壤在自然荷载和技术荷载影响下的行为进行了建模。根据模拟结果,确定了在附加荷载影响下变形标志的变化,这可能是Dnister上部水库的填充。显然,单独使用这种方法无法完全探测和跟踪现代地质、地震和地球动力学过程。对不同的监测方法(地球物理、大地测量、参数、测振、水文地质、温度、视觉仪器等)进行组合和详细分析,以及在自然和技术因素的影响下对物体的行为进行建模,是最佳的。这种模拟可以用于其他此类物体的设计,因此这是一个很有前途的进一步研究领域。独创性在研究测斜观测数据的基础上,首次对Dnister PSPP自然和技术系统区域内分散土壤的行为进行了数学分析和预测。实际意义。所提出的技术可用于其他此类物体的设计,因为对物体在自然和技术因素影响下的行为进行建模,可以评估和预防可能的风险。
