Temperature controlling for high grade concrete of C60 in large section;

The workmanship with large section rectangular pipejacking is hereby described regarding the engineering practice t.

The large cross section conductor technology can be used to substantially increase the transmission capacity of overhead lines, and can solve the contradiction between the large demand for transmission capacity and the limited line corridors.

Based on the comparison between two different single mode conditions for rib waveguides with large cross section,the conditions given by Pogossian et al and its errors are analysed.

The main technique parameters and application of large cross-section fiber bundles are introduced.

1 000 kV UHV AC substation is adopted with the large cross-section soft-bus conductor.

Quality control in the manufacture and use of large size ACSR;

In terms of large size multi-core pre-fabricated branched cables,this paper explores the key manufacturing processes for the main cable and branch,conductor crimping and insulation of the connection box.

This text brought forward a new method using compand-silk fiber to fabricate big section optical fiber image transmitting bundle through the research on the craft of small section optical fiber image transmitting bundle using acid-leaching method.

Strength calculation of axial compressive RC members strengthened with increasing section method;

Several strength methods for concrete structures such as CFRP,increasing section and bonding steel plates are intruced to(appling) in an uncompleted building which is demanded to add six storeys.

The research method and process about reinforcing and increasing bearing capacity of rigid-frame arch bridge by increasing section technique are introduced.
