针对地质力学参数识别问题中通常基于原位位移的观测点优化布置问题，提出了一种新的优化布置方法。从参数辨识的过程中的解的存在性，唯一性和稳定性进行了深入的讨论。基于这些问题的理解，提出了两种算法作为自动生成最佳测量的手段。通过算例验证了算法的有效性，并将其应用于慕尼黑地铁隧道工程。在那里观察到了良好的结果。
This paper focuses on designing the optimal layout of measurements for parameter identification problems in geomechanics, which are usually based on in situ displacements. The existence, uniqueness, and stability of the solution from the parameter identification process are thoroughly discussed. Based on these understandings of the problem, two algorithms are proposed as a means of automatically generating the optimal measurements. The validity of these algorithms is first proved by some academic examples, then these algorithms are applied to the Munich subway tunnel project. Good results are observed there.
