谈大连地区岩溶地貌桥梁工程桩基础设计

Discussion on karst topography bridge engineering pile foundation design in Dalian region

分析了大连地区岩溶地貌的特点,探讨了该地区桥梁工程桩基础的设计方法,结合实例,论述了直接穿洞法与多桩固定法的优缺点,指出应根据场地的地质条件,做好实地勘察,并在此基础上进行桥梁桩基设计,才可保证设计方案的科学性。

The thesis analyzes karst topography features in Dalian region, and explores bridge engineering pile foundation design methods in Dalian region. Combining with example, it discusses merits and defects of direct piercing method and multi-pile fixing method, and finally points out that： it is necessary to do well in field survey according to the field geology conditions and to carry out bridge pile foundation design, with a view to guarantee the design scheme scientific.
