摘　　要：在传统应力恢复法基本原理的基础上，提出了改进的应力恢复法。通过室内试验求出了改进应力恢复法的关键系数——应力等效系数，并运用数值模拟进行检验，同时分析了其影响因素及影响程度。通过现场实践，证明了改进应力恢复法的可行性和正确性，具有重要的理论意义和实用价值。This paper presents an improved stress restoring method based on the basic principle of the historical stress restoring method, obtained the improved stress restoring method's key coefficient - stress equivalent coefficient and makes inspection utilizing numerical modeling. At the same time, the paper analyses its affecting factor and degree, and it's feasibility and rightness were tested by field practice. It has important theorical and practical value.
