摘要:
针对当前在地震作用下岩溶加固地基抗震构造的评估模型评估范围不全面，导致评估结果准确性低下的问题，提出地震作用下岩溶加固地基抗震构造评估模型分析。采用莫尔—库仑理论，根据岩溶塌陷地质形成因素，计算岩溶顶板安全厚度的极限承载能力，分析岩溶顶板稳定性，由岩溶顶板抛物线拱力学模型，计算压力拱高度变化取值，完成岩溶顶板注浆加固机理研究，分析地震作用下的抗震构造可靠性，建立岩溶加固地基抗震构造评估模型。实验结果表明，所设计的地震作用下岩溶加固地基抗震构造评估模型，与传统相比所得到的评估范围更加广泛，使评估结果更加精准。由此可见，此模型更有效果。
Abstract:
Aiming at the problem that the seismic structure evaluation model of karst reinforcement foundation under earthquake is not comprehensive and the accuracy of evaluation result is low，this paper puts forward the seismic structure evaluation model of karst reinforcement foundation under earthquake. Using the mohr-coulomb theory and according to the geological formation of karst collapse factors，the paper calculates the ultimate bearing capacity of roof karst with the safe thickness，analyzes the karst roof stability，calculates value of the pressure arch height change basing the karst parabolic arch roof mechanics model，completes the karst roof grouting reinforcement mechanism research，analyzes the seismic structural reliability under earthquake，and establishes the model of the karst foundation aseismic structure reinforcement. The experimental results show that compared with the traditional evaluation model，the designed evaluation model for the seismic structure of karst reinforced foundation is more extensive，which makes the evaluation result more accurate. Thus，this model is more effective.
