The invention discloses a method for calculating the slope stability safety coefficient based on strength reduction of a humidifying condition. The method comprises the steps of testing the dry density rhod, the natural moisture content omega1, and the percentage of saturated moisture content omega2 of a slope soil body sample, testing the cohesive force c and internal friction angles of samples with different moisture contents, and calculating the volume weight gamma of the samples, wherein the formula of internal friction angles is shown in the description; drawing the relation curves of the cohesive force c and the internal friction angles respectively with the moisture content omega, and obtaining a mathematic formula of a fitting relation curve; adopting a dichotomy approximation method and considering the volume weight change, and calculating the moisture content omegaF when the slope is in critical failure; calculating the slope stability safety coefficient F. According to the method for calculating the slope stability safety coefficient based on the strength reduction of the humidifying condition, anti-shearing strength of the slope soil body is reduced based on the humidifying condition, the method better conforms to the engineering practice that the moisture content of the soil body is increased, and thus the strength is lowered due to rainfall infiltration or irrigation or the like, and the shortcoming that a prior strength reduction method is not clear in mechanical concept is overcome. When strength reduction is conducted, the adverse influence of the increase of the volume weight of the soil body on the slope stability is further considered. Therefore, the method for calculating the slope stability safety coefficient based on the strength reduction of the humidifying condition is more scientific and safer.

Neural network device for evolving appropriate connections

A system and method for evolving appropriate connections in feedforward topological networks. FIG. 1 illustrates an exemplary flow diagram of a method for evolving appropriate connections in a neural network device according to an aspect of the present invention. Initially, weight changes induced by each particular training sample or pattern are calculated using, for example, a conventional network training rule such as Hebb or backpropagation (step 101). Next, a ratio of the weight changes for existing connections to incipient connections ("K" ratio) is calculated (step 103). If this K ratio exceeds a specified threshold, weight changes are implemented (step 105), in which existing weights are increased by (1-E)x(total weight change of existing connections), where E is a network-wide parameter. The remaining amount (E)x(total weight change of existing connections) is added to form neighboring connections (step 107). It is to be noted that if neighboring connections are not yet in existence (i.e, they are incipient connections), they can be created by this mutation rule; however, whether such new connections are created depends on the size of the weight increase computed in step 101, together with the magnitude of E. After cycling through a training set, connections that are weak (e.g., weaker than a specified threshold) are deleted (step 109). Following step 109, the system returns to step 101. Advantageously, a system and method according to the present invention allows a combination of the advantages of fully connected networks and of sparse networks and reduces the number of calculations that must be done, since only the calculations corresponding to the existing connections and their neighbors need be determined.
