The invention discloses a live broadcast room recommendation method, storage medium, electronic equipment and system, and relates to the field of big data recommendation, which can recommend the user's preferred live broadcast room for the user according to the specified live room, and specifically includes the following process: according to the preset The assumed live room quality scoring process calculates the quality scores of N live rooms, where N is an integer greater than 1, and the N live rooms are groups of live rooms to be scored. Calculate the similarity of the common label between each live room in the live room group to be rated and the specified live room. Input the quality score and the similarity of the common label into the preset recommendation index algorithm to obtain the recommendation index of each live room in the live room group to be rated. The live broadcast rooms whose recommendation index exceeds the preset recommendation index threshold are used as the recommended live broadcast rooms, or the recommendation indexes are sorted, and the preset number of live broadcast rooms with the highest ranking are used as the recommended live broadcast rooms. The present invention can better calculate the similarity between live broadcasts.

The invention relates to the field of stability evaluation of rock mass slopes, and aims to provide an evaluation method for the stability of curved toppling rock mass slopes with a large degree of curvature. Including: (1) Obtaining the stratum parameters of layered rock slope; (2) Dividing the free bending area and the coordinated bending area; (3) Testing the stability of the free bending area; (4) Calculating the interaction between rock layers in the coordinated bending area (5) Judging the stability of the rock formation at the foot of the slope and the entire slope. Because the bending degree of the rock formation of the large deformation toppled slope is relatively close to the circular arc shape, the present invention improves the limitation of the cantilever beam method by assuming the rock formation as a circular arc on the basis of the traditional linear cantilever beam method, making it Capable of evaluating toppled slopes with large degrees of curvature. Due to the concise formula and few required rock parameters, the method of the present invention is time-consuming and low-cost; the calculation is objective and does not need to manually set parameters; and it can accurately calculate the stability of a curved toppling slope with a large degree of curvature.
