摘要

The subway project crossing Beijing-Zhuhai expressway employed pipe-roof to push a box-culvert of the largest cross-section in Asia at present into soft clay stratum located in Zhengzhou. The main issue considered both in the design and construction is the control of the stratum displacement to keep the safety of the expressway. Based on the in-situ measured data, the numerical simulation of the stratum displacement during the whole construction process is studied systematically by using FLAC 3-D computer program. By combing the analysis and comparison of the site measured results and numerical stimulation results, the stratum displacement patterns are summarized, and they have guiding significance for the design and construction in the future.
