摘　　要：为反映地基加固深度对软土地基综合管廊结构受力性能的影响,以广州大学城综合管廊为例,通过对加固综合管廊断面宽度范围内的土体进行仿真模拟,研究了地基加固深度(0~4.8 m)对软土地基综合管廊结构受力性能的影响。分析表明:综合管廊结构竖向位移和宽度范围内的地表土体竖向位移随地基加固深度的增加而线性减小;地表竖向位移受地基加固深度的影响较大,而在综合管廊宽度范围外,地表竖向位移随地基加固深度的增大而减小,但其受地基加固深度的影响较小。In order to reflect the impact of foundation reinforcement depth of soft soil pipe gallery structure stress performance,taking Guangzhou University city tube corridor as an example,through the simulation of soil reinforcement pipe gallery section width within the scope of the study the foundation reinforcement depth(0-4.8m)effect on the soft soil foundation of comprehensive pipe gallery structure stress performance the.The analysis shows that the surface soil vertical displacement comprehensive pipe rack structure vertical displacement and width range with the reinforcement depth of foundation increases linearly decreases;the vertical displacement of the ground surface is greatly affected by the reinforcement depth of foundation,and in the comprehensive pipe gallery width range,the vertical displacement of the ground surface increases with foundation reinforcement depth decreases,but the smaller the influence of foundation reinforcement depth.
