静力触探在合芜高速公路工程勘察中的应用

Application of static cone penetration test to the ground investigation of Hefei-Wuhu Expressway

静力触探是一种快速的原位测试方法,具有设备简单、轻便、机械化和自动化程度高、操作方便,可直接取得数据等优点。实践证明,在合芜高速公路软土地区公路工程地基勘察中初步应用静力触探的效果是显著的。用静力触探和工程地质钻探、取样及试验相配合的方法效果良好,提供了更为准确的设计参数,提高工效2～4倍,取得了良好的经济效益和社会效益。

As a quick insitu testing means,the static cone penetration test is simple, convenient, highly automatic and easily operational in terms of the equipment it requires,and the test data can be gained directly. The static cone penetration test is applied here to the investigation of the ground of HefeiWuhu Expressway in the soft soil area. It is found out that the static cone penetration test in combination with the engineering geological drilling, sampling and experiment can produce a good result,the design parameters can be offered more accurately,and the work efficiency be raised by 2 to 4 times,so good benefits are achieved both economically and socially.
