　　为进一步破解龙岩大道高架桥主桥桩基溶洞问题，加快施工进度，促使施工范围道路及早畅通，9月17日，市住建局邀请贵州、深圳等岩溶发育地区多名岩溶处理专家和召集相关单位技术负责人，召开龙岩大道高架桥工程主桥桩基溶洞处理专家会，对主桥桩基施工遇到的溶洞问题进行技术论证。

　　龙岩大桥主桥跨越龙津河、两条城市主干道和两条铁路，是贯通南北向交通的控制性工程。自施工以来，由于遭遇复杂的溶洞地质条件，工程进展一度缓慢。今年6月中旬以来，在桩基施工78米至85米处时，遇到穿越斜岩面的困难，采用反复回填仍无起色。经过专家考察与设计、施工单位充分交流讨论后，专家们一致建议：结合已有勘察资料，对下部溶洞的贯通及溶洞顶板情况重新进行补充勘察，再次明确地下溶洞的发育情况，后期结合现场实际，拟用钢护筒处理，以期能够顺利穿越溶洞，加快大桥主桥施工进度。
