摘要
介绍了某大桥工程围堰设计方案及渗流方案比选。在抗浮防渗方面,比较了混凝土封底方案以及减压抗浮方案的优缺点,确定了以减压抗浮方案为工程的防渗方案;在比较了传统钢板桩施工工艺与新型的钢板桩施工工艺后,确定了以新型的钢板桩围堰施工工艺进行钢板桩围堰的建设。
This paper describes the scheme comparison of a bridge cofferdam design and seepage. In terms of anti- floating impermeable, the advantages and disadvantages are compared about concrete cover and decompression anti floating scheme. The decompression anti floating scheme is determined for seepage control scheme of anti floating engineering. After comparing the traditional and the new cofferdam construction technology of steel sheet pile, the new cofferdam construction technology of steel sheet pile is used.
