چکیده

موقعیت سطح بحرانی شکست و ضریب اطمینان کمینه مربوط به آن، دو جزء مکمل در تحلیل پایداری شیروانیهای خاکی هستند. برای یافتن سطح بحرانی شکست، اغلب از روشهای جستجوی مختلفی مانند جستجوی شبکه‌ای استفاده می‌شود که بدین منظور نرم افزارهای رایانه‌ای متعددی تا کنون تهیه شده و در بیشتر این نرم افزارها، از روشهای جستجوی بی‌اعتبار و غیرقابل اطمینان استفاده شده است. در این مقاله، از روش مونت‌کارلو که روشی مؤثر و معتبر است، استفاده می‌شود و در نهایت اعتبار این روش مورد بررسی قرار گرفته است.

چکیده [English]

Locating the critical slip surface and the associated minimum factor of safety are two complementary parts in a slope stability analysis. A large number of computer programs exist to solve slope stability problems. Most of these programs, however, have used inefficient and unreliable search procedures to locate the global minimum factor of safety. This paper presents an efficient and reliable method to determine the global minimum factor of safety coupled with a modified version of the Monte Carlo technique. Examples are presented to illustrate the reliability of the proposed method.
