The Construction Analysis of the Basement of Narrow Space Super High-rise Building is Made
This paper takes a super high-rise building as an example,analyzes the construction technology of semi-reverse method in the base-ment of the super high-rise building with narrow construction space,large foundation pit depth and close to the subway,and tests the actual application effect.The results show that the maximum horizontal displacement of the basement supporting pile is 12.3 mm,the maximum verti-cal displacement is 5.6 mm,the maximum settlement of the surrounding buildings is 4.8 mm,and the maximum settlement of the surrounding roads is 6.8 mm,all of which fail to reach the warning value and meet the requirements of the design scheme,indicating that the construction effect of the semi-reverse construction technique is good.
