某圆形特小断面特长引水隧洞的工程造价问题

摘要

结合某圆形特小断面特长引水隧洞工程实例，对工程造价中存在的定额子目与现场不匹配、工效低、施工组织困难、排风排烟难度大、费用相差大等问题进行了分析，以提出合理的解决措施，从而根据实际情况调整工程造价。%Combining with the example of some circular super-small section super-large water diversion tunnel,the paper analyzes some problems in the engineering cost,including inconsistent quota and site,low construction efficiency,difficulties in construction organization,ventilation and smoke discharge,and big differences in cost,so as to point out reasonable measures and adjust the engineering cost according to the fact.
