[ 1 ] - پیش‌بینی ظرفیت باربری جانبی شمع‌ها در خاک‌های رسی با استفاده از ماشین بردار پشتیبان
پیش‌بینی ظرفیت باربری شمع‌های تحت بار جانبی یکی از مسائل اساسی در مهندسی ژئوتکنیک است و تاکنون روش‌های متفاوتی برای ارزیابی آن ارائه شده است. ماشین بردار پشتیبان (SVM) یک روش نسبتاً جدید هوش مصنوعی است که در بسیاری از مسائل ژئوتکنیکی به طور موفقیت‌آمیزی مورد استفاده قرار گرفته است. این مقاله کاربرد مدل SVM برای پیش‌بینی ظرفیت باربری جانبی شمع‌ها در خاک‌های رسی را شرح می‌دهد. از نتایج مدل‌های کوچ...
[ 2 ] - Bearing Capacity of Shallow Foundations on Cohesionless Soils: A Random Forest Based Approach
Determining the ultimate bearing capacity (UBC) is vital for design of shallow foundations. Recently, soft computing methods (i.e. artificial neural networks and support vector machines) have been used for this purpose. In this paper, Random Forest (RF) is utilized as a tree-based ensemble classifier for predicting the UBC of shallow foundations on cohesionless soils. The inputs of model are wi...
[ 3 ] - Prediction of maximum surface settlement caused by earth pressure balance shield tunneling using random forest
Due to urbanization and population increase, need for metro tunnels, has been considerably increased in urban areas. Estimating the surface settlement caused by tunnel excavation is an important task especially where the tunnels are excavated in urban areas or beneath important structures. Many models have been established for this purpose by extracting the relationship between the settlement a...
[ 4 ] - Evaluation of liquefaction potential based on CPT results using C4.5 decision tree
The prediction of liquefaction potential of soil due to an earthquake is an essential task in Civil Engineering. The decision tree is a tree structure consisting of internal and terminal nodes which process the data to ultimately yield a classification. C4.5 is a known algorithm widely used to design decision trees. In this algorithm, a pruning process is carried out to solve the problem of the...
