Foundation pit construction faces complex site conditions and difficult construction techniques.In this paper,a foundation pit construction risk assessment system is constructed to evaluate and solve the risk evo-lution based on the fuzzy analytic hierarchy process(FAHP).This risk assessment system covers six risks inclu-ding construction organizational risk(personnel),engineering environmental risk(environment),construction technology risk(technical),construction operations risk(mechanical),site management risk(management)and construction quality risk(material).Taking a foundation pit construction of a newly built reclaimed water plant as an example,the risk level is assessed,and the key risk factors are analyzed.This study provides refer-ences for the design and construction of foundation pit.
