摘要
岩溶地区由于地质条件复杂多变,且不确定因素较多,施工难度大,如果对岩土工程条件认识不足,选用的施工方法不当,就会造成严重的质量安全隐患和经济损失。以京福高速公路三明段将乐玉华洞大桥为例,介绍了在岩溶地质条件下钻孔灌注桩的施工特点,以及施工中应采取的预防和处理措施。
Because cavern rock region, s geology circumstance is complicated and variational, construction more difficulty. If we didn＇t learn about lithofacies and adopted unapt construction method, the economic loss and severe quality safety problem will occur, The paper takes Yuhuadong big bridge on Jingfu expressway as the example, and introduces construction characteristics of drilling and casting pile under the cavern rock region geologic condition, and suggests prevention measures in construction.
