杭州全面启动“地质体检”

Core Insights - Hangzhou has launched a comprehensive "geological health check" to assess urban geological safety risks, aiming to enhance urban resilience and safety over a two-year period [1] Group 1: Project Overview - The geological health check is likened to a CT scan of the urban geological environment, aiming to systematically understand the underground structure and identify anomalies [1] - A visualized 3D model will be established to represent underground resources, space, and safety, thereby improving urban governance and resource utilization [1] Group 2: Historical Context and Achievements - Since 2004, Hangzhou has undergone two rounds of urban geological surveys, creating holographic images of key areas like Qianjiang New Town and the Olympic Sports Center, achieving centimeter-level precision in subsurface structure mapping [2] - The city has developed a dynamic digital platform that updates data on geological safety risks and monitoring points, including 90 underground water monitoring points and 500 subsidence monitoring points [2] Group 3: Future Plans and Goals - The pilot project aims to integrate geological survey results into urban planning, major project site selection, land storage, underground space development, and public transportation [2] - The initiative will enhance the geological safety monitoring network, optimize risk zoning, and establish a comprehensive prevention and control standard system, contributing to the construction of a smart and resilient city [2]
