About this document

Microtunneling Risks in Boulder Conditions by swhunt is a document available to read on EtoBox.

This document provides an overview of microtunneling projects that encountered cobbly and bouldery ground conditions. It discusses the key factors to consider when assessing risk for these conditions, including geology, cobble and boulder properties, quantities and distributions. Boulder volume ratio is presented as a useful metric to characterize cobble and boulder concentrations, with examples given from past projects showing typical ratios encountered. The strengths of cobbles and boulders can vary depen
