The hydrofracturing technique is the most effective measuring method in the geostress measurement in deep stratum. 在深層地應力測量中，水壓致裂法是最有效的測量方法。
The theoretical model created based on minimum principal stress criteion is a new thinking of the three dimensional geo-stress measurements made by hydraulic fracturing method. 采用最小主應力破壞準則，建立理論模型，是利用水壓致裂方法進(jìn)行三維地應力測量的新的研究思路和方法。
