摘要
文章结合相关文献和资料对Goodman单元理论进行了优化改进,利用有限元数值模拟法对贵州市某土石坝防渗墙加固水库工程的应力变形进行模拟计算,并模拟分析了防渗墙与土体之间的接触面特征;然后分别针对正常蓄水位和校核洪水条件下的防渗墙横向应力应变进行求解和确定,分析对比了实测值与计算值之间的差异并验证了该方法的可行性与准确性;研究成果可为防渗前提在水利工程除险加固中的应用提供一定参考和依据。
In this study,the Goodman unit theory is optimized and improved with relevant literature and data. The finite element numerical simulation method is used to simulate the stress and deformation of the seepage control wall of a rock-fill dam in Guizhou,and the characteristics of the contact surface between the impervious wall and the soil are simulated and analyzed,and then the normal water storage is carried out respectively. The lateral stress and strain of the seepage proof wall under the condition of the flood and the check flood are solved and determined. The difference between the measured value and the calculated value is analyzed and compared,and the feasibility and accuracy of the method are verified. The results can provide some reference and basis for application of the seepage prevention precondition in the reinforcement of water conservancy project.
