The main objective of this paper is to investigate the dynamic performance and behaviour glass-fiber reinforced plastic (GRP) mortar pipes under heavy truck loads. According field conditions, a finite element analysis (FEDA) model GRP pipe culverts was established. Modal vibration system carried out, natural frequencies with 26.6Hz,32Hz,35.7Hz corresponding mode shapes were obtained. On ...

Soil–steel composite bridges (SSCB) have become increasingly popular for short-span as an alternative to concrete slab mainly due their low initial cost, rapid manufacture, simplified construction, and geometrical adaptability. SSCBs a variety of applications can be used over waterways or roadways. While conventional tend lose load-carrying capacity degradation, gain strength because backfill s...

In this paper, the behaviour of pipe roof method with different roofs disposition schemes including gate system and L-shaped is discussed in terms ground settlement reduction condition underground space construction adjacent to existing structure by using numerical simulation method. Considering sequences parallel tunnels rectangular cross sections, appropriate parameters response characteristi...

Soil Erosion is the detachment, transportation and deposition of soil sediment from one place to another. This has led loss lives infrastructure in many parts Nigeria. properties play a role it vulnerability extent erosion. study aims evaluate selected physical as they interact cause erosion area. The was conducted 2012 gully site relation its potential erodibility channel. done by collection v...

The construction of a new CFPP in Indonesia, which was located next to three existing power plants and utilized an discharge channel, faced the problem insufficient capacity channel deliver water four plants. occurred not only because overcapacity cooling flow proposed by but also small size culvert channel. This paper discusses several methods overcome this enlarging area or removing from repl...

In arid regions, the construction of hydraulic structures is relevant due to shortage water resources. Using example Pskov hydroelectric power station, results calculation end structure energy spillway, made in form a well unique design, are presented. A culvert wall, with an initial expanding part and sloping spillway forming oblique forms well. The depths speeds each parameters jump calculate...
