摘　　要：详细介绍了香港科技大学(广州)深厚淤泥基坑工程的设计实践。探讨了对淤泥流变、施工应力及深层滑动等不利影响进行控制的关键技术措施,以及支护管桩与旋喷锚索的设计问题。采用弹性支点法(m法)、有限元法与剪切位移法计算支护结构的受力与变形,并将计算结果与锚索基本试验结果、监测结果进行比对,三者总体吻合良好。The design practice of deep silt foundation pit of HKUST in Guangzhou was introduced in detail.The key technical measures for controlling adverse effects such as silt rheology,construction stress,and deep sliding were discussed,as well as the design issues of support pipe pile and jet grouting anchor cable.The elastic fulcrum method(m method),finite element method,and shear displacement method were used to calculate the force and deformation of the support structure.The calculation results were compared with the basic test results of anchor cable and monitoring results,and the overall agreement between the three are good.
