This research is to establish a general validity of in situ calibration technique and compare the predicted and measured soil response. The research will be completed in three phases. The first phase evaluates the theoretical feasibility of the approach for in situ calibration of selected soil constitutive models, taking into account the variations in soil parameters. The followup phases will construct a laboratory model of the in situ calibration device and carry out field verification tests to verify the performance of the models under in situ conditions.

本研究旨在建立一种普遍有效的原位校准技术，并比较预测和实测的土壤响应。研究将分三个阶段完成。第一阶段在考虑土壤参数变化的情况下，评估了所选土壤本构模型原位校准方法的理论可行性。后续阶段将构建现场校准装置的实验室模型，并进行现场验证试验，以验证模型在现场条件下的性能。
