摘要: 城市地下交通网络快速扩张,地铁建设频繁穿越地质复杂区域,易引发地面沉降及存在建筑物结构损伤等安全隐患。昆明市作为典型高原断陷盆地城市,地铁系统面临独特地质挑战,本文旨在解析地铁沿线形变时空分异规律与演化趋势,定量解析驱动机制,为地铁规划和灾害预防提供依据。InSAR技术因大范围、高精度监测能力,成为城市基础设施形变监测重要手段。选取昆明地铁沿线为研究对象,融合多源SAR数据,提出异轨多源InSAR点云融合方法,并利用GIS空间分析技术,结合地表覆盖等四维驱动因子体系开展研究。本文研究揭示了昆明市地铁沿线形变的时空演变格局,识别出主要驱动因素,为地铁规划和灾害预防提供了科学依据。

Abstract: The rapid expansion of the urban underground transportation network and the frequent crossing of subway construction through complex geological areas can easily lead to potential safety hazards such as ground subsidence and structural damage to buildings.As a typical plateau fault basin city,Kunming faces unique geological challenges with its subway system.This study aims to analyze the spatio-temporal differentiation patterns and evolution trends of deformation along the subway line,quantitatively assess the driving mechanisms,and provide a basis for subway planning and disaster prevention.InSAR technology has become an important tool for monitoring deformation in urban infrastructure due to its large-scale and high-precision monitoring capabilities.This study selects the area along the Kunming metro as the subject,integrates multi-source SAR data,and proposes a cross-track multi-source InSAR point cloud fusion method.Using GIS spatial analysis techniques and incorporating a four-dimensional system of driving factors such as land cover,and is conducted.It reveals the spatio-temporal evolution patterns of deformation along the Kunming subway and identifies the main driving factors.This provides a scientific basis for subway planning and disaster prevention.

Key words: PS-InSAR, Kunming metro, multi-source SAR data, GIS analysis, driving factors
