| description | The invention relates to a method for evaluating undrained shear strength of clay by using a liquid-plastic limit combined tester. The method comprises the following steps: selecting a clay sample for testing; measuring the undrained shear strength of the soil sample by using a Norway drop cone instrument; based on the measured undrained shear strength of the soil sample, calibrating an empirical coefficient K of the liquid-plastic limit combined determinator; on the basis of the empirical coefficient K, a liquid-plastic limit combined tester is adopted for testing, and the undrained shear strength of the clay is calculated through the formula Su = KQ/h2. The method is high in accuracy, the test cost can be greatly reduced, and specific experimental instruments do not need to be purchased independently.
本发明涉及一种利用液塑限联合测定仪评估黏土的不排水抗剪强度的方法，包括如下步骤：选取黏土的土样进行试验；利用挪威落锥仪测定土样不排水抗剪强度；基于测定的土样不排水抗剪强度，标定液塑限联合测定仪的经验系数K；在经验系数K的基础上，采用液塑限联合测定仪进行试验，并通过公式Su＝KQ/h2计算黏土的不排水抗剪强度。本发明准确性高，且可以大幅度减少试验成本，不需要单独购买特定实验仪器。 |
