西安咸阳机场三期扩建智慧跑道地基沉降监测方案设计与优化

Design and Optimization of Ground Settlement Monitoring Scheme for Intelligent Runway of Xianyang Airport Phase Ⅲ Expansion

西安咸阳机场三期扩建规模大、地基处理和地质条件复杂,对机场建设期和运营期地基沉降变形控制要求高。利用智慧跑道建设契机,机场针对湿陷性黄土、填挖交界、下穿工程、新老交界等工程难点,采用场道地基沉降变形监测新技术,构建了建设-运营一体化地基沉降智能监测设计与优化方案,为控制机场场道沉降变形、提升建设、运营安全性提供技术保障。

Xi’an Xianyang International Airport’s Phase Ⅲ expan sion is large in scale,complicated in foundation tr eatment and geological conditions,and has a high requirement for foundation settlement deformation control during the construction and oper ation periods.Airport takes the opportunity of smart runway construction to adopts the multi-sour ce technology of foundation settlement deformation monitoring and builds an integrated construction-operation foundation settlement monitoring design and optimization plan for engineering difficulties such as collapsible loess,fill-dig junction,under-passing projects,old and new junction,etc..It provides technical guarantee for controlling airport field settlement deformation and improving construction and oper ation safety.
