施工组织设计是初步设计文件的重要组成部分。它是一门研究工程设计发包前的施工条件、优化工程建设的施工方案、讲求建设中的经济效益和探讨现代施工管理的科学。施工组织设计不能代替施工单位的施工措施计划,但它是编制初步设计概算和施工措施计划的主要依据;是施工单位据以施工的战略步骤;是建设单位制订年度计划、主管单位作出有关决策的准绳;是编制招标承包文件的基础。水利水电建设,施工条件差,项目多,结构复杂,工程量大,施工期长,还受水文、气象、地形、地质等自然条件限制,因而,在施工组织设计中通过优化施工方案,选用可能获得的新型材料和先进设备,有效地综合平衡人、财、物力,合理安排时间和空间,使施工单位能组织科学管理,文明施工,以求获得最大的经济效益,最优的工程 Construction organization design is an important part of the preliminary design documents. It is a research project before the contract construction conditions, optimize the construction of the construction program, pay attention to the economic benefits of construction and explore the modern construction management science. The construction organization design can not replace the construction unit’s construction measures plan, but it is the main basis for compiling preliminary design estimates and construction measures plans; it is the strategic steps for the construction unit to be constructed accordingly; it is the construction unit’s annual plan for the competent unit to make relevant decisions Standard; is the basis for the preparation of the tender contract. Water conservancy and hydropower construction, poor construction conditions, many projects, complex structure, large quantities, long construction period, but also by hydrology, meteorology, topography, geology and other natural conditions, therefore, in the construction design through the optimization of construction programs, the selection of possible The new materials and advanced equipment obtained effectively balance human, financial and material resources and make reasonable arrangements for time and space so that construction units can organize scientific management and civilized construction so as to obtain the maximum economic benefits. The optimal engineering
