摘要
通过定性的力学分析、原理性的模型试验、工程动载试验、数值计算分析4个方面的研究,论述了在地层介质中应力、加速度的传递与介质的相对刚度密切相关,提出固体介质中应力、加速度传递的观念,及其相应的广义复合结构体系;在地下工程、防护工程建设中,若能正确的运用这种观念。
∶ Based on investigation into four aspects of qualitative mechanical analysis, principle model experiments, engineering dynamic load tests and numerical calculation, it was discussed that the transfer of stresses and accelerations in stratum medium have a close relation with its relative rigidity. The concepts of stresses and accelerations transfer in solid medium and its corresponding generalized, composite structure system are presented. The survivability of underground engineerings and protective engineering will be greatly increased if these concepts are correctly used in construction.
