工程地质岩组定量划分的多元数据最优分割法

Optimal cut-part method for driving of engineering geology groups of rock masses

摘要: 提出了划分工程地质岩组的多元数据最优分割方法。根据现场测得的岩体的三种定量指标(岩体超声波波速、岩石点荷载强度及岩石质量指标 (RQD)),运用多元数据最优分割方法进行岩体的工程地质岩组定量划分。并用此方法对润扬长江公路大桥地基岩体进行了详细的岩组划分,划分结果为确定基础持力层和设计参数提供了重要依据。

Abstract: This paper presents optimal cut-part method for driving of engineering geology groups of rock masses.Based on field measured data of 3 variables（supersonic wave velocity of rock masses,rock point load compression strength,rock quality designation）,the results of driving into groups of rock masses in Runyang Yangtze River Highway Bridge Project are given.
