城市地下空间开发利用的地质安全评价内容与方法为题目，写不少于1200的论文 Introduction Thedevelopmentandutilizationofundergroundspaceinurbanareashasbeenincreasinglyrecognizedasaviableoptionforaddressingurbanspacelimitations,congestion,andovercrowding.Citiesaroundtheworldhavebeenexploringwaystomaximizetheuseofundergroundspaceforvariouspurposes,includingtransportation,storage,recreation,andhousing.However,thedevelopmentofundergroundspacealsopresentsvariouschallenges,includinggeologichazardssuchassubsidence,sinkholes,androckfall.Therefore,geologicalsafetyevaluationsarecrucialtoensurethesustainableandsafeutilizationofundergroundspace. Thispaperaimstodiscussthecontentandmethodsofgeologicalsafetyevaluationsforurbanundergroundspacedevelopmentandutilization.Specifically,itwillcoverthekeygeologicalhazardsthatneedtobeassessedandprovideanoverviewofdifferentevaluationtechniquesusedintheindustry.
