A good many case of approaching excavation are studied in this article, such as the study of infection of be coal mining to the huayingshan tunnel, technology study of strucked tunnels of metro in shenzhen, countermeasure study of tunnel approaching pile foundation of metro in guangzhou, excavation methods optimized of large cross section subaqueous tunnel approaching pile foundation of lrt in chongqing, etc. on the basic of analysing and concluding relative study production all over the the world by the numbers, classification of approaching excavation, partition of approach zone, formula of partition of approaching zone, approach degree and countermeasure grade of generalized approaching excavation of underground works are put forward. general methods studying and trea
本文結合作者多年來對華鎣山隧道減少壓煤量研究、深圳地鐵重疊隧道第11頁西南交通大學博士研究主學位論文技術研究、廣州地鐵公紀區間廣紡聯段鄰樁施工對策研究和重慶輕軌大坪大斷面車站鄰近基礎淺埋暗挖工法優化分析等諸多近接施工問題案例的研究，在系統分析和歸納總結國內外相關研究成果的基礎上，系統地提出了廣義的地下工程近接施工的分類、分區、分區指標表達式、近接度與對策等級概念以及分區、分度準則，給出了研究和解決近接施工問題的普遍方法，如數值分析先行，模型試驗、現場測試驗證等。 -
By analyzing the several finished bridge projects, if the hollow pile foundation is adopted, we can economize subaqueous concrete consumption more than 40 per cents ; if the gr outed new technique of pile surroundings and pile toe is adopted, we can increase the load capacity 30 per cents than that of the replacement pile, and economize 20 per cents of the cost. it will show great and obvious economic and social benefits
