摘要：
针对龙厦铁路DK35+607～DK36+028段U形槽混凝土挡墙出现开裂问题，通过采用埋入式混凝土应变计进行量测混凝土应变，得出混凝土内部应力应变分布规律及随时间的变化规律，分析计算出混凝土挡墙可能开裂区域的部位、时间及原因，提出控制变形开裂的措施，可为类似工程的施工提供一定的借鉴。

Abstract:
n order to cope with the cracks of the concrete retaining walls of the "U"shaped road channel from DK35+607 to DK36+028 on LongyanXiamen Railway, embedded concrete strain gauges are used to measure the concrete strains. The distribution pattern and timedependent varying pattern of the internal stresses and strains of the concrete are obtained. The position, time and cause for the probable cracking zones of the concrete retaining walls are analyzed and countermeasures are proposed to control the cracks. This paper can provide reference for similar projects in the future.
