For reducing cost and accelerating construction speed sparingly , at present in irrigation works construct in producing testing progressively and antiabrasion layer that popularize excavating method competent to split law in advance , flexible cushion layer etc . accumulative charge to vertical hole has been tested in three gorege project only 为了节省施工成本、加快施工进度，目前在水利工程施工生产中逐步试验并推广的保护层开挖方法有水平预裂法，柔性垫层法等。对于垂直孔水平聚能药包爆破用于生产试验仅在三峡进行过。
Firstly , it aims at the deficiency in cost managing of the project items in our country from the objective and subjective ways . the objective is the system of the lowest acceptance and growing material price and the system of cash guarantee ; the subject is the weaker cost managing and wrong reorganization of cost managing and the weaker controlling cost and neglecting the analyses of the other cost except for 客观方面分析了最低价中标制度、原材料价格上涨、现金保证金制度三个市场因素,主观方面从成本管理意识薄弱、在工程成本管理认识上的误区、成本管理体制的不完善、成本控制能力的薄弱、忽视除施工成本对的其他成本的分析控制、成本管理计算手段落后、缺乏分析检查机制等七个方面进行了的分析和探讨。
Based on the prediction of both the external economic factor of market and the internal management factor of enterprise which influence the construction cost directly , the control criteria for the project construction cost can be precisely determined ; by which not only the blindness of cost payout can be avoided , and the scientific prediction cart also be enhanced with the realization of the target control of the management cost concerned 摘要项目施工成本预测的内外因素的主要内容是，通过对影响成本变化的外部市场经济因素和企业内部管理因素的预测，可以较准确地确定工程施工成本的控制标准，克服成本支出盲目性，提高科学预见性，实现管理费的目标控制。
For a specific project , the construction cost of the project can be reasonably and scientifically analyzed and estimated by means of the reasonable planning for the resources allocation adaptable to the project made through the economic assessment on the conduction process ; by which the cost control indexes can be determined , the relevant internal checking mechanism and the budget system for construction cost control can be established , and then the avoidable measures for possible economic risk can be made as well , so as to obtain the benefit indexes adaptable to all the specific items to realize the management of the construction cost control for the whole construction process and build up the scientific and reasonable system of economic responsibility for making a basis for completing the project with better quality effectively , economically and reasonably 摘要通过项目的过程经济评佑，制定出适应工程项目的合理资源配置计划，对具体工程项目的施工成本进行合理、科学的分析判断，确定成本控制指标，建立施工成本控制内部考核机制和工程施工成本预算制度，找出具体子项的经济风险源所在，建立相应的经济风险规避措施，获取适应每个具体项目的利润指标，实现工程项目施工全过程的施工成本控制管理并建立科学合理的经济责任制，以便调动项目部所有施工人员的创造性和主动性，为最终高效、经济合理、保质保量地完成工程施工任务奠定基础。
