本文对现有的水压致裂三维地应力测量方法进行了深入的力学分析，在此基础上提出了新的理论模型。新的理论模型采用了最小主应力破坏准则，与现有方法采用的最小切向应力破坏准则相比，更客观的表述了水压致裂过程中的力学机制。为说明该方法的工作步骤及其可行性，文中利用遗传算法反演技术，对假设的地应力状态进行了试算。试算结果表明该方法是可行的。
In this paper, in-depth mechanical analysis of the existing three-dimensional method of measuring fracturing hydraulic fracturing has been carried out. Based on this, a new theoretical model has been proposed. The new theoretical model adopts the principle of minimum principal stress failure. Compared with the minimum tangential stress failure criterion adopted by the existing methods, the mechanics mechanism in hydraulic fracturing process is more objectively described. In order to illustrate the work steps and the feasibility of the method, genetic algorithm inversion technique is used in this paper to test the assumed state of geostress. The trial results show that this method is feasible.
