下部结构

The emphasis is put on the analysis of seismic response influence due to design parameters of substructure.

重点进行了下部结构设计参数对直连续刚构桥和弯连续刚构桥的抗震性能影响分析。

After examines calculated that, this bridge substructure design is reasonable.

经过检算，该桥的下部结构设计较为合理。

And then calculated and analyzed is the force of piers, bents and foundations of lower structure.

对下部结构桥墩，桥台和基础作出了详细的内力计算与验算。

Among them, the plain section of the embankment, small bridges and culverts have been completed in part; the lower part of the structure of the bridge project has been completed 95% of the total; tunnel works completed 40% of the total project.

其中，平原区段的路基、小桥涵部分已经基本完成；桥梁下部结构已完成工程总量的95%；隧道工程完成工程总量的40%。

The substructure uses the distyle bridge pier, the pillar foundation is a pile foundation.

下部结构采用双柱式桥墩，墩基础为桩基础。

The type of structure can achieve light-duty of girders, thus reduces the engineering work of its substructure.

这种结构能够实现主梁的轻型化，进而减轻下部结构的工程量。

First, on the basis of sufficient study on the constructive condition of the main bridge of Tianxingzhou Bridge, different types of cross section of the steel truss beam, relationship between the length of steel beam node and quantity of steel, the shape of pylon, the form of anchorage and the structural system of the main bridge of Tianxingzhou Bridge are analysed.

本文以天兴洲大桥主桥的设计为研究对象，较为详细的研究了以下内容：首先，在充分研究天兴洲大桥具体建桥条件的基础上，研究了不同主桁断面形式，比较了各种节间长度对受力及用钢量的影响，分析了主塔的形式和索的锚固方式，对比分析主桥总体布置的不同方案，同时还对主桥下部结构方案进行对比分析；然后，对不同铁路结合桥面布置方案进行了对比研究，并计算了推荐方案在不同荷载工况下的受力状况。

This paper introduces dismantling design and construction of the trestle bridge,and puts emphasis on reinforcement design in dismantling construction of the trestle bridge,dismantling construction gist of road plates of bridge,Bailey beams and steel pipe piles.

栈桥桥面宽8·0m，按双车道设计，顶面设计标高为7·0m。栈桥为多跨连续梁，梁上部结构为单层321贝雷桁架，梁高1·5m；栈桥跨径有12m及15m两种；下部结构采用打入式钢管桩基础，按摩擦桩设计，桩径分800、600mm两种，桩长20~40m。

In the other method, the priestesses steel rods are placed in the lower part of a form that corresponds to the shape of the finished structure, and the concrete is poured around them.

在其他的方法，女祭司钢筋放置在一个窗体对应的成品下部结构的形状，而周围的混凝土浇。

The design was focused on the substructures of Yalongjiang Bridge.

本设计为雅砻江大桥主桥下部结构。
