                      我國高速公路大多采用的是“波形梁護欄”,中央隔離帶護欄主要為雙波波形梁護欄。根據國內外護欄安全性能評價的標準來看,在高速條件下,雙波波形梁護欄主要防護的對象是小型車。也就是說,如果重型車輛或者大型客車在較高時速下與此類護欄發生碰撞,護欄無法達到有效防護。
                      Most of the expressways in our country use the "wave beam" guardrail, and the median guardrail is mainly double wave wave beam guardrail. According to the safety performance evaluation standards of guardrails at home and abroad, under the condition of high speed, the main protection object of double wave beam guardrails is small cars. In other words, if heavy vehicles or large buses collide with such guardrails at high speed, the guardrails can not achieve effective protection.
                      據數據統計,我國高速公路雖然只占公路總里程的2.4%,卻完成了全社會營業性貨車40%的貨物周轉量。且在我國高速公路網中,部分地方貨車流量占比甚至超過40%。但是,我國高速公路現有大多數中央隔離帶的雙波波形梁護欄無法滿足這些重型車輛的運行安全需求,存在此類沖破中央隔離帶護欄的事故風險
                      According to statistics, although China's expressways only account for 2.4% of the total mileage of highways, they have completed 40% of the freight turnover of commercial trucks in the whole society. And in China's highway network, the proportion of freight traffic in some places is even more than 40%. However, most of the existing double wave corrugated beam guardrails in the median of expressways in our country can not meet the operation safety requirements of these heavy vehicles, and there is such an accident risk of breaking through the median guardrail
