Based on the geometric meaning of reliability index, a global optimization algorithm is proposed to calculate the reliability index and design checkpoint of geotechnical engineering by using the principle of genetic algorithm. This method simulates the process of biological genetic evolution and overcomes the shortcoming of the traditional method that it is easy to fall into the local minimum. For the non-linearity and complexity of function functions, the derivation of the derivative is sometimes avoided. The effectiveness of the method in this paper is proved by examples
