文档介绍：摘要
本工程位于贵阳市南部,跨越鱼梁河。该桥位处土质主要为亚粘土和亚砂土,表层土CBR值普遍较低;运河经过场地内,地下水水质对混凝土无腐蚀性,对钢结构具弱腐蚀性。地震基本烈度7度。--,主要受大气降水补给,根据水质分析资料,地下水对混凝土不具有腐蚀性。本工程所在地为贵阳市,位于贵州中部,地处华中地区,温带大陆性气候,°C ,最低气温-11°C ,°C ,年平均降水量792mm,多集中在7、8月份。
上部采用15×30m十五跨预应力混凝土连续梁,梁体采用C50预应力混凝土T形梁,梁高2m。
为圆满完成贵州关堰大桥工程,根据招标文件,在认真阅读和充分理解设计意图及对施工现场作详细调查的基础上,并结合我单位的施工经验,以信守合同、确保工期和质量、合理控制工程造价、优质高效文明施工为指导思想,编制本工程施工组织。在编制过程中,我们立足于专业化、机械化、标准化、科学化施工,重点工序重点安排,特殊部位特殊考虑,并结合工期和工程实际进行统筹,尽量做到现场布置合理,方案切合实际,施工组织科学得当,以便为优质高效完成该项工程奠定基础。

Abstract
This engineering locates GuiYang downtown south, crossing over the river of Zhang . The bridge is located at the sub-soil is mainly clay and sandy loam, surface soil is generally low CBR values; canal through the site, the groundwater quality of the concrete non-corrosive, corrosion of steel with weak. Basic seismic intensity 7 degrees. Groundwater depth - for the upper discharge, mainly due to precipitation recharge, water quality analysis data according to groundwater is not corrosive to concrete. The project location is in Guiyang City, Guizhou Province is located in the central part is located in the central region, temperate continental climate, annual average temperature of ° C, minimum temperature of -11 ° C, maximum temperature of ° C, average annual rainfall of 792mm, mostly concentrated in 7,8 month. Top with 15 × 30m 15-span prestressed concrete beam, prestressed concrete beams using C50 T-beam, high beam 2m.
Weir for the pletion of the bridge project in Guizhou, according to tender documents, carefully read and fully understand the design intent and detailed investigation on the construction site on the basis bined construction experience of my unit, to abide by the contract, to ensure the duration and quality, and reasonable Control project cost, quality and efficient construction of civilization as the guiding ideology, the preparation of the anization. In the preparation process, we base ourselves on
