汾江路南延线沉管隧道砂基础模型礎研究

Study on Sand Foundation Model Test of Immersed Tunnel of Fenjiang Road South Extension Line

本文依托汾江路南延线沉管隧道工程,建造其单孔压砂等比例模型,采用变化砂水比的压砂工艺,考虑压砂过程中抗浮系数影响进行了相关试验研究。试验结果可为汾江路南延线沉管隧道及类似工程砂基础设计与施工提供借鉴与参考。

In this paper,relying on the immersed tube tunnel project on the south extension of Fenjiang Road,the scale model of single-hole sand pressure is built,and the sand pressure process with varying sand-water ratio is adopted,and the relevant experimental research is carried out considering the influence of the anti-floating coefficient during the sand pressure process.The test results can provide references and references for the design and construction of sand foundations for immersed tube tunnels and similar projects on the southern extension of Fenjiang road.
