Relocating the Forest to Minimise the Effects of Earthworks and Accelerate the Restoration of Environmental Compensation

The construction of new roads or the widening thereof often has significant environmental impacts. To reduce these impacts, the approach used in environmental assessments is first to avoid them, then to minimise them through mitigation measures, and finally to compensate for any residual losses. In a context of climate crisis and biodiversity loss, the wooded natural habitat component is becoming increasingly important in environmental assessments.

The Consideration of Live Loading in the Design and Assessment of Earth Structures

The design of Earthworks and Earth Structures involves the determination of forces from dead loads, predominantly the ground, but also consideration of transient live loads, predominantly traffic loading. The determination of live traffic loads in Earthworks has been taken from those used by structures engineers in the design of bridge decks and retaining walls.

Use of geosynthetics for more resilient infrastructure

Natural catastrophes, e.g. extreme weather conditions or destructive seismic events, can cause enormous damage or the collapse of infrastructure objects, resulting even in heavy losses of human lives. Typically, engineered slopes and bridges are a very sensitive part of the infrastructure, particularly exposed to climate-change. Geotechnical damage with multiplying effects is normally caused by heavy rainfalls and storms leading to floods and consequent scouring of infrastructure objects.
