The aims of the present paper are (i) to briefly review single-field and multi-field shotcrete models proposed in the literature; (ii) to propose the extension of a damage-plasticity model for concrete to shotcrete; and (iii) to evaluate the capabilities of the proposed extended damage-plasticity model for shotcrete by comparing the predicted response with experimental data for shotcrete and with the response predicted by shotcrete models, available in the literature. The results of the evaluation will be used for recommendations concerning the application and further improvements of the investigated shotcrete models and they will serve as a basis for the design of a new lab test program, complementing the existing ones.
（i）简要回顾文献中提出的单场和多场喷射混凝土模型；（ii）将混凝土的损伤塑性模型扩展到喷射混凝土；（iii）通过将预测响应与喷射混凝土的实验数据以及文献中可用的喷射混凝土模型预测的响应进行比较，评估所提出的喷射混凝土扩展损伤塑性模型的能力。评估结果将用于对所研究的喷射混凝土模型的应用和进一步改进提出建议，并将作为设计一个新的实验室测试程序的基础，以补充现有的测试程序。
