The circular arc method and the improved circular arc method are applied to calculation of the safety factor of embankments respectively, and the calculated results by the two methods are compared for different material parameters, different dam slopes, different interlayer embedded depths, and different earthquake forces.
Taking the Biot's consolidation theory as a basis, adopting the visco-elastic constitutive model , using the two dimensional finite element method ,in this paper the stability under the static and dynamic conditions of the Yakou landslide is calculated. Comparison is made with the calculating result of the Bishop circular arc method and the unbalanced force transmitting coefficient method, and the stability of the Yakou landslide has been assessed.
This paper introduces the major steps and principle of drawing the measured stratigraphic section by using the circular arc method with a microcomputer. The concept of the sector is introduced in the method;
In slope stability analysis,disproportion thrust method(such as the Swedish circle method and the Bisho method) and finite element method are usually adopted,which have no essential difference but both have shortcomings in calculation.
On the establishment of mathematical model of slope stability analysis, the theory adopted conventional limit equilibrium method -Swedish circle method(Fellenus) as the main analysis model, then simulates organic evolution process, optimizes model with the horizontal、 vertical ordinate and radius of slip circle center as search variable based on genetic algorithm, accordingly obtained a kind of slope stability analysis evaluation method that can search the most dangerous sliding surface of slope in global ranger and calculate minimum safety coefficients based on local convergence.
A comparison is made in this paper on the theory and calculation of three methods commonly used in slope stability analysis, namely, Swedish circle method, simplified Bishop's method and Janbu method. Besides, the influences of thrustline assumption in Janbu method, earthquake loading, and pore water pressure parameter (?) , on the safety factor of slope are studied.
The so-called "principal term" of Goldbach problem, i.e., the principal order of the number of representations of an even number as a sum of two primes, is evaluated here in a way quite different from the classical circle method.
This general result isestablished via a suitable adaptation of the Hardy-Littlewood Circle Method.
A method of stability analysis of the pile-reinforced slopes has been derived by extending the friction circle method of slope stability analysis in conjunction with the pile stability analysis proposed by Ito and Matsui.
The definition of a strongly Hardy-Littlewood variety is given in such a way that varieties for which the Hardy-Littlewood circle method is applicable are strongly Hardy-Littlewood.
Objective: A radiological study was performed to evaluate ulnar variance in 68 Dutch patients using an electronic digitizer compared with Palmer's concentric circle method.
