The paper refers to experimental results on rock foundations of 500KV transmission lines which belong to nation s major projects, and analyzes types of group anchorage foundation, mechanism of destructive phenomena, influence factors of bearing capacity, and calculation methods of bearing capacity.

The construction condition,technology and procedure for steel pipe concrete pile supported by anchor foundation at the north,Renyang Bridge and the quality detection are introduced in the paper.

For the concreting construction and running process of north anchor foundation of Runyang suspension bridge,the three-dimension finite element simulation model considering the interaction of anchor foundation and soil is founded based on the secondary development of Marc.

As a main bearing structure of suspension bridges, the stability of anchor foundations is very important.

Research on mechanical properties of frozen curtain in large anchorage foundation pit engineering

This paper deals with the design and construction of the key sectional works,the round diaphragm wall and its inner lagging and bottom sealing,of the south anchorage foundation of Yangluo Changjiang River Highway Bridge.

The south anchorage foundation of the Suspension Bridge of Runyang Changjiang River Highway Bridge is a huge and deep foundation built in the weak soil ground and keyed into the underlying rock thereof.

The rock anchorage base can be applied on the transmit electricity engineering of middle and heavy weathering area.
