Combining with geology of the problem areas and surveying a short distance of a highway tunnel dense cracks,we can check construc-tion defects determine the main causes of lining cracks,at the same time developping appropriate reinforcement measures for the lining cracks formed in different areas and reasons,after processing,implement special testing and monitoring about the areas to verify the treatment effect,to ensure the cavern safety,achieve the desired objectives.%通过对某高速公路隧道短距离密集裂缝的现场调查，结合问题区域地质情况，分析了衬砌裂缝形成的原因，并针对不同形式，不同区域的衬砌裂缝，制定了相应的加固补强措施，处理完毕后，对该区域实施专项检测及监控，验证处理效果，确保洞室安全，达到预期目的，结果较为理想。
