Abstract

A structural and ground investigation was carried out on a domestic property at Leigh, Lancashire, England. The settlement of the property was measured and showed a complex pattern of movement which was separated into: (i) an overall tilt towards the east; (ii) an outward tilt of the northern and southern ends; and (iii) severe tilting and cracking at the northern end. Following detailed investigation separate causes were assigned to each of these movements as: (i) preferential longwall mining to the east of the site; (ii) eccentric loading at the northern and southern ends; and (iii) moisture removal from the stiff clay beneath the northern end by the roots of a nearby tree. Details of the settlement of the property, soil conditions and mining situation are presented together with appraisal and analysis of the separated movements.

Diagnosis of Structural Damage and Movement Due to More Than One Cause

A structural and ground investigation was carried out on a domestic property at Leigh, Lancashire, England. The settlement of the property was measured and showed a complex pattern of movement which was separated into: (i) an overall tilt towards the east; (ii) an outward tilt of the northern and southern ends; and (iii) severe tilting and cracking at the northern end. Following detailed investigation separate causes were assigned to each of these movements as: (i) preferential longwall mining to the east of the site; (ii) eccentric loading at the northern and southern ends; and (iii) moisture removal from the stiff clay beneath the northern end by the roots of a nearby tree. Details of the settlement of the property, soil conditions and mining situation are presented together with appraisal and analysis of the separated movements.
