The article introduces the special-purpose utensils and installations of using common level to monitor building base subsidence in high precision.

The soil liquefaction due to earthquakes will usually result in the damage of caisson foundation.

The caisson foundation construction of Changchun light railway cable-stayed bridge without back-stays;

By the formula of criterion,the safety factors of the stability against sliding and overturning are computed for one anchor caisson foundation.

Study on penetration resistance distribution characteristic of sunk shaft foundation;

The rebuilding scheme fully considers the harmony of the whole bridge with the surrounding environment, meets the planned traffic function requirements and the relative technical standards, puts forward the design of the steel composite beam structure for the main bridge and the technical measures taken for the sunk shaft foundation treat.

In this article, the author analyzes some aspects of false centers in construction of sunk shaft foundations such as formation, reasons and hazards, and states matters need attention in construction and prevention and correction measures.

This paper analysed stability and structural calculation of sunk well foundation and its application in the discharging sluice of Shuang Yanghe river.
