Analysis of the current construction performance of the Great Wall of China in Jinshanling

Abstract

This research study focuses on the Jinshanling segment of the Great Wall of China. Site investigations, data collection and non-destructive examinations of various parts of the structure have resulted in a detailed analysis of the performance of both the wall and the towers of the Jinshanling segment. A satisfactory performance can be attributed to the use of rubble-filled core and bedrock foundations, levelled stone and brickwork, and lower-density materials towards the top of the structure and large columns to support heavier loads within the towers, among other factors. Suggested causes for deterioration of the wall include design issues and construction workmanship, lack of post-construction maintenance, natural weather and other events. The overall performance of the middle Jinshanling section of the Great Wall is satisfactory, but renovations are needed in both the eastern and western Jinshanling sections to prevent further damage.
