The extraordinary activity of taphrogenic differential settlement of late caused great damage and economy loss to urban building, it will greatly jeopard the tunnel engineering recently .

The process of taphrogenic differential settlement can be regarded as limited system.

The process of taphrogenic differential settlementcan is regarded as a complicated hazard phenomena,and it may be merged into a limited system with finite life span.

Cracking is mainly due to dry/wet cycling, physicochemical reaction and different settlement.

The different settlement factors of the columns are analyzed and some useful control measures are enumerated.

Influence of differential settlement on pavement structure in expressway widening project;

Piled raft with gap between pile top and raft to adjust differential settlement;

The research of differential settlement of composite piled foundations;

Firstly, the problem of settlement difference between the new pa.

Combining with wide application of the enlarge base multiple tower structure form in district design,it aims at several common problems in this kind of project design,such as confirming of fixity position,treatment of basic settlement differences and measures of structure super length provides suggestions,so as to improve application of the enlarge base multiple tower structure.

When the main body structure of a building had been finished,it was found that there were cracks in a part of frame girders,and there were great uneven settlement and the settlement speed that didn t meet the requirment.

For non-uniformity of soil strength at Chengdao Sea of Shengli Oilfield and the rupture of pipeline induced by foundation uneven settlement, one method to access the pipeline safety induced by uneven settlement was put out in this article.
