The impact of heavy traffic on forest soils: A review
Soil compaction and rutting are the most common effects of traffic. • Soil compaction limits oxygen and water supply to plants and soil microorganisms. • Forest Abstract The compaction of agricultural soils cannot be solved, only managed. As a compressible media, soil travel without causing some collapse of the Reducing Soil Compaction from Equipment to Enhance

Experimental research on a novel soil displacement
The soil displacement monitoring equipment can be pre-embedded or implanted in the ground to monitor both horizontal and vertical soil displacements. The DEM modeling of SPMI systems mainly involves the study of soil interaction with biological plant materials and machine components. Specifically, soil–machine, soil–plant, and plant–machine interactions are Agronomy Free Full-Text Modeling

In an ideal soil, about half of the pore space is filled with water and half with air. Pore space is essential for plant growth, providing space for plant roots to grow.Soil Properties, Part 1 of 3: Physical Characteristics

Experimental investigation of batter pile groups behaviour subjected
ABSTRACT. A series of laboratory model tests on batter pile groups embedded in the sand was carried out in a specially designed testing box. The lateral responses were investigated for 1 × 2 capped batter pile groups when subjected to lateral soil movements (passive loading) with different configurations; Vertical-Vertical (VVL), Batter-Vertical (BVL), Soil is moved during many agricultural activities; of these, tillage is the most prevalent. Tillage is used in seedbed preparation, seed placement, nutrient placement and incorporation (fertilizerSoil Movement by Tillage and Other Agricultural Activities

Review of Discrete Element Method Simulations of
In mechanized agriculture, the energy use for soil tillage operations can be as high as 50% of the total energy used in crop production [1,2].The energy-use efficiency associated with tillage can be Intensive forestry operations may cause soil compaction, plastic soil disturbances and rutting, which are responsible for undesirable effects on soils, vegetation and water bodies. Despite the numerous studies aimed to identify the main factors affecting soil damages, it still remains unclear whether wood extraction methods and driving Impacts of wood extraction on soil: assessing rutting and soil

Lateral Soil Movements Due to Pile Driving: A Case Study in
Due to concerns about potential additional lateral soil movement, the subsequent phase of pile driving was monitored with vibration monitoring equipment, piezometers, and inclinometers in the ground between the pile driving and the retaining wall. The authors analyzed the raw monitoring data and compared them with predictions of Examples of Soil Movement in a sentence.

Trenching and Excavation Toolkit NAHB
Keep heavy equipment away from trench edges and identify other sources that might affect trench stability. Keep all spoils piles and equipment at least 2 ft. away from the edge of the excavation. Use stairs, ladders, and ramps every 25 ft. to exit the excavation. Do not stand beneath loads handled by lifting or digging equipment.Rolling dynamic compaction is a soil compaction technique which involves compacting the ground with a heavy, non-circular module. Compared with traditional compaction methods, it is, in most cases, more efficient, as it improves the soil to a greater depth and it facilitates more rapid ground improvement due to its higher travel speeds. Investigating the effectiveness of Rolling Dynamic Compaction

Accounting for Expansive Soil Movement in Geotechnical
Lightweight structures built on expansive soils are susceptible to damage caused by soil movement. Financial losses resulting from the improper design of structures on expansive soils can be significant. The interactions and failure mechanisms of different geotechnical structures constructed on such soils differ depending on the structure type, Soil conservation is done using mechanical or non-mechanical methods. The non-mechanical method is a long-lasting process, and its effectiveness increases gradually. The purpose of non-mechanical conservation is to prevent soil degradation or to prevent the erosion from spreading at the very beginning of its emergence.Soil Conservation Using Mechanical and Non-mechanical
