Foundation Optimization for Two Blocks of High-rise Residential Buildings |

| Abstract: | After detailed geo-tech investigation,site test and data assessments for strong weathered rock stratum,the foundation of two blocks of high-rise residential buildings are optimized from bored piles to raft on strong weathered rock.Some critical technical challenges and their practical solutions are demonstrated and discussed,such as evaluation of bearing stratum capacity,stability of raft with insufficient embedded depth required by the codes of practice,as well as settlement estimation.Records of settlement survey are presented,together with feedback analysis based on survey data.The statistic method to site investigation data is recommended for future settlement estimation. |

| Keywords: | foundation optimization raft foundation embedded depth of foundation subgrade stability coefficient of subgrade reaction settlement estimation |
