| 中文摘要: |
| 土围堰和钢板桩围堰均为常用的围堰结构形式，当两者用于施工方案比选时，除考虑平面布置、结构稳定性分析和施工方案等方面外，工程造价也是施工方案选择必须考虑的重要因素。为选择更为经济的施工围堰方案，结合工程案例，分析施工方案、土地征用、主材供应等方面对工程造价的影响。结果表明，对于土方缺乏且围堰拆除后土方无法消纳的航道工程，钢管桩围堰具有节约用地、节省造价的优势；对于土方供应充足且围堰拆除后土方容易消纳的工程，可优先选用土围堰施工方案。 |
| 英文摘要: |
| Soil cofferdam and steel sheet pile cofferdam are both commonly used cofferdam structures,when the two are used for comparison and selection of construction scheme,in addition to the plane layout,structural stability analysis and construction schemes,the project cost is an important factor to be considered in the construction scheme selection.To choose a more economical construction cofferdam scheme,this paper analyzes the influence of construction scheme,land requisition,main material supply and other aspects on the project cost by combining with an engineering case.The results show that when the waterway engineering is short of soil and unable to absorb the excavated soil after the cofferdam is demolished,the steel sheet pile cofferdam has the advantage of saving land and cost.For the waterway engineering with sufficient soil supply and the excavated soil can be absorbed after the cofferdam is demolished,the soil cofferdam can give priority to be used. |
