石膏模型试验在国内外已广泛应用于解决坝工结构的应力、变形、稳定等问题,特别在空间结构和复杂地基的应力分析方面,更有其现实意义,这是有限单元法计算所不能取代的。模型试验还是校核理论计算和评价新的设计方法的重要手段之一。坝工结构内部应力的研究,要求解决模型内部应变的测定问题。目前利用内埋电阻丝片量测石膏模型内部应变的 The gypsum model test has been widely used at home and abroad to solve the problems of stress, deformation and stability of dam structures, especially in the stress analysis of space structures and complex foundations, which is of practical significance because of the finite element method of. Model testing is also one of the most important means of checking theory to evaluate and evaluate new design methods. The study of internal stress in dam structure requires solving the problem of measuring the strain in the model. Current use of embedded resistance gages measuring gypsum model internal strain
