建设二路站的施工组织设计

摘要基坑工程是集地质工程、岩土工程、结构工程等诸多学科领域于一体的一项系统性工程。然而基坑工程通常设计难度较大，对于施工的工程技术也有较高的要求，这是因为基坑工程受工程地质条件和现场建构筑物的制约，表现出了很大的个体差异性，因而设计和施工都需要兼顾多方因素的限制，加之如今相关领域的理论模型尚不完善，也给施工带来了安全隐患。因此对于基坑工程而言，合理的结构设计、规范有序的施工和对现场的监测都显得尤为重要。本文的主要内容如下：(1)根据已有的工程地质资料，依据相关技术规范和工程经验，合理的进行了基坑围护结构的设计和验算，确定了结构的稳定可靠。(2)拟定了施工组织方案，以便施工作业能够在保证工程质量的前提下，规范有序的推进。(3)针对本项目的施工制定监测方案，阐述了基坑监测的对象、方法、频率和质量控制要求，以便可以及时排查施工现场的安全隐患和结构的缺陷，关键词：基坑工程：结构设计与验算：施工组织设计：基坑的监测IAbstractFoundation pit engineering is a body of engineering in geology,geotechnical engineeringand structural engineering,and many other disciplines,which integrates a systemicengineering.Foundation pit engineering design usually is difficult,however,for the constructionengineering technology also have higher request,this is because the foundation pit engineering isconditioned by engineering geological conditions and the field of architectural structures,showed great individual differences,which need both design and construction of the limitation ofvarious factors,combined with relevant theoretical model in the field of now still is not perfected,also brings to the construction of the security hidden danger.So for the foundation pitengineering,the reasonable structure design,standard and orderly construction and monitoringof the scene is particularly important.The main content of this paper is as follows:(1)Based on existing engineering geologic data,based on relevant engineeringspecifications and engineering experience,the reasonable design and calculation of retainingstructure of foundation pit,determine the structure is stable and reliable.(2)To formulate the construction organization plan,so that construction work can be on thepremise of guarantee the engineering quality,standard and orderly progress.(3)Monitoring for the project construction,this paper expounds the foundation pitmonitoring objects,methods,frequency,and quality control requirements,so as to timelyscreening potential safety hazard of the construction site and structure defects,Key Words:Foundation pit engineering;Structural design and calculationConstruction organization designing The foundation pit monitorinΠ目录摘要...IAbstract......................第1章绪论…。1.1研究的内容及意义1.2国内外研究现状与发展趋势1.3拟采用的技术路线.3第2章工程资料与施工方案的比选42.1工程资料…42.1.1主要建构筑物及市政管线042.1.2主要地层资料…52.13水文地质资料….82.2特殊性岩土与不良地质作用影响分析与评价2.3施工方案的比选2.3.1顺作法与逆作法的比选.................112.3.2基坑支护方案的比选2.4本章小结.13第3章基坑支护构件设计与验算….143.1计算利用断面….143.2荷载计算的理论与方法…143.2.1土压力的计算….143.2.2水压力的计算，.183.2.3地面超载及周边地面建筑附加荷载193.3基坑和围护结构的稳定性分析与内力验算203.3.1支护模型的建立与工况的输出验算203.3.2沉降验算.243.3.3整体稳定验算，.263.3.4抗倾覆稳定性验算..283.3.5抗隆起验算313.3.6抗管涌验算333.4地下连续墙配筋计算。343.4.1起点端头井配筋计算.343.4.2中间段配筋计算.373.4.3终点端头井配筋计算.…39第4章施工组织与监测方案的制定424.1施工准备..........424.2施工方法及主要步骤434.3施工的技术要求及注意事项434.3.1地下连续墙施工顺序434.3.2导墙施工…444.3.3混凝土的浇筑..444.4施工部署和总平面图444.5施工进度计划与保证措施.454.5.1施工进度计划.….454.5.2工程质量与安全保证措施........................464.6基坑监测的目的及意义…464.7基坑监测的仪器准备与监测项目64.7.1现场安全巡视….474.7.2地表沉降.….474.7.3地下管线沉降.48
