在原位十字板与静探数据的相关性分析中,考虑研究范围内土体强度可分别由两种测试数据独立线性表达,找出两种试验指标的等式,将试验参数综合考虑,建立多元线性回归方程,通过大量试验数据并借助数学软件对回归方程进行求解。通过实例分析,验证两种试验关系的准确性,为今后的勘察与研究提供参考和新的方法。
在原位十字闆與靜探數據的相關性分析中,攷慮研究範圍內土體彊度可分彆由兩種測試數據獨立線性錶達,找齣兩種試驗指標的等式,將試驗參數綜閤攷慮,建立多元線性迴歸方程,通過大量試驗數據併藉助數學軟件對迴歸方程進行求解。通過實例分析,驗證兩種試驗關繫的準確性,為今後的勘察與研究提供參攷和新的方法。

In the research on the correlation between in - situ vane shear strength and static cone penetration strength , considering the soil strength can be expressed by either of the two tests' data in the test range, an equation could be found with parameters of two tests, with comprehensive consideration on the test parameters, the linear regression equation has been established and has been solved based on massive test data. The conclusion has been drawn that the linear correlation between the two tests has a good accuracy, and the paper provides refer- ences and a new way for further exploration and research.
