为改进冻结壁厚度的设计方法,通过假设经验地压取值存在一定的误差限,对冻结壁厚度的经典弹性、弹塑性和流变理论设计进行了相应误差分析.结果表明:虽然冻结壁设计理论不断发展,但若地压取值存在误差,经典弹性模型、弹塑性模型和流变模型的冻结壁厚度相对误差也会超过10%,甚至20%.地压误差对冻结壁厚度理论设计的影响较大,甚至导致相应理论模型失效.由此可能造成深井造价大幅提高,并增加安全隐患和引发重大事故的可能性.
In order to improve the design method of the frozen wall thickness, the corresponding error analysis of the classic elastic, elasto-plastic and rheological design of the frozen wall thickness is carried out by assuming that there is a certain error limit of the empirically obtained value. The results show that although the design of the frozen wall However, if there are errors in the pressure values, the relative error of the frozen wall thickness of the classical elastic model, elastic-plastic model and rheological model will exceed 10% or even 20%. The influence of the ground pressure on the frozen wall thickness theory The impact is even larger, and even the corresponding theoretical model is invalid, which may result in a substantial increase in the cost of the deep well and increase the potential for safety hazards and major accidents.
