DEM Analysis of Backfilled Walls Subjected to Active Translation Mode
In this paper, the problem of a retaining wall under active translation mode is investigated numerically. To this end, a series of numerical models is conducted using the discrete element code, PFC2D. The backfill soil is simulated by an assembly of separate cohesionless circular particles. Backfill soil was prepared by pouring soil particles from a specific height under gravity force and givin...
متن کاملLiroo dam abutments leakage analysis using DFN-DEM hybrid method
The Liroo Dam is one of the largest concrete dams in the country under study. The objective is to investigate and estimate the amount of water leakage from joints and fractures in dam abutments using numerical method. Interconnected fractures are the main pathways of water flow into the abutments and control the rock hydraulic behavior. Considering the stochastic properties of the geometric par...

در این تحقیق شبکه عصبی مصنوعی برای پیش بینی مقادیر ضریب اطمینان و فاکتور ایمنی بحرانی سدهای خاکی ناهمگن ضمن در نظر گرفتن تاثیر نیروی اینرسی زلزله ارائه شده است. ورودی های مدل شامل ارتفاع سد و زاویه شیب بالا دست، ضریب زلزله، ارتفاع آب، پارامترهای مقاومتی هسته و پوسته و خروجی های آن شامل ضریب اطمینان می شود. مهمترین پارامتر مورد نظر در تحلیل پایداری شیب، بدست آوردن فاکتور ایمنی است. در این تحقیق ...
Woody debris
1. Maximum rate of cut that would provide a hillslope landslide rate of <20% over background, assuming no areas are protected by no-cut buffers .. Summary Downstream impacts to aquatic environments and property generally occur as cumulative watershed impacts, which are usually caused by changes in the transport of woody debris, water, and sediment through a watershed. The downstream cumulative ...
متن کاملWoody debris research: Overview
Fallen woody debris, standing dead trees (taller than 1.3 m) and stumps (shorter than 1.3 m) constitute a large portion of total above-ground carbon in tropical and temperate forests (Keller et al. 2004; Rice et al. 2004). In addition to being an important carbon pool, aboveground necromass is important in nutrient cycling, water retention, fuel load, and as resources for many organisms. Despit...
