| 摘 要： | 目前高速公路中央分隔带波形梁护栏立柱的实际设置中,普遍存在着由于分隔带地基强度低于压实路基,护栏立柱承载能力偏低,护栏的防护性能达不到设计要求的问题。本文对粘性土地基中立柱的受力情况进行了分析,并对地基为压实土与回填土两种情况进行了对比,给出了中央分隔带中立柱地基的加固方案。

| Abstract: | From the accident data, the main safety problem associated with highway medium guardrail in China now is the lack of the strength of the post抯 base soil. The effort in this paper is concentrated on the study of stability of the guardrail post during collision process of uncontrolled cars with the guardrail structure. An analysis of fencepost in clay base is given. The situation in backfilled clay base is compared with that of the compacted, and a reasonable reinforce scheme is given. |
