Study on the Analysis of Pile Foundation Deformation and Control Methods during the Excavation of Deep and Thick Sludge Pits

Dengqun Wang,
Shuaihua Ye,
Liangliang Xin

Abstract: This study aims to apply performance-based safety-assessment methods to the monitoring and numerical simulation of excavation engineering projects in order to comprehensively enhance engineering risk management and decision support. In this paper, a deep excavation project in Hefei with thick silty clay layers was studied. The analysis included the surface settlement, the deformation of support structures, the vertical and horizontal displacements of pile tops, axial forces in steel braces, settlement, and the… Show more

“…Based on actual monitoring data, they investigated the changes in the support structure, surrounding buildings, and groundwater level during the excavation process. Wang et al [6] took a deep foundation pit project in a deep silty clay layer in Hefei as the research object. Using on-site monitoring data, he analyzed the surface settlement of the foundation pit, the deformation of the support structure, the vertical and horizontal displacement of the pile top, the axial force and settlement of the steel support, and the horizontal displacement of the gravity retaining wall on the south side of the foundation pit.…”
