Settlement analysis and underpinning reinforcement of building foundation

Hanbin Wang

Abstract

By analyzing the reason that the groundsill of some building subsides,it is found that the main reason bringing on the subsiding is the sinking of back-filing and underlayer of yellow earth under the groundsill thick back-filing above it as well as the thick high-compressible back-filing under the groundsill; besides,compared the method of grouting with that of micro-pile underpinning,the method of micro-pile underpinning was adopted to reinforce the constructure with the underpinning design.
