圆锥动力触探成果在碎石土勘察中的应用
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 7
Abstract
重型及超重型圆锥动力触探试验是碎石土地基勘察的有效手段，但在通常勘察中，人们常仅把圆锥动力触探成果作为地基土求取参数的定性参考数值，有时即便用圆锥动力触探数值在规范表格中查得地基承载力及变形参数，却因数值远大于实际数值，而不得不弃用。本文从圆锥动力触探的原理、应用入手，以工程实例分析动力触探数值常常偏大的原因及处理办法，实现动力触探成果与地基土力学参数之间合理的转换关系，以推进对圆锥动力触探试验在岩土工程勘察中更好、更准确地应用。
