摘要
十字板剪切试验(VST)是原位测试手段之一,对测定饱和软粘性土的抗剪强度和残余抗剪强度、地基承载力、判断软土固结程度、灵敏度、计算路基稳定性等方面有很好的效果。该文结合武汉四新地区工程实践来具体介绍十字板剪切试验在软土地基勘察的应用。
VST is one of in-situ tests methods,and it has good effect for saturated soft clay to test shear strength,residual shear strength,bearing capacity of foundation,judgment of consolidation degree,sensitivity and calculation of subgrade soil stability.Combined with Sixin engineering practice in Wuhan,the application of VST in the investigation of soft subsoil is introduced.
