一、概况本市海塘堤坡上建有不同类型护坡结构工程——干砌块石、浆砌块石、灌砌块石、灌砌块石表面加压不同消浪块体等。灌砌块石和浆砌块石护坡下部反滤层,常因护脚底部抛石消失而造成垫层流失,形成空洞隐患。而且隐患在表面不易发现,一旦隐患出现,险情就较严重,且危及人民生命财产。例如,2000年“派比安”和“桑美”两次台风袭击横沙岛,发现浆砌块石护坡塌陷严重,有的造成大堤部分破口,但平时该段表面看来完好无损。如何探测发现隐患,及早预防是十分必要的。为
First, an overview of the city built on the seawall dike different types of slope protection works - dry stone masonry, masonry masonry stone, irrigation stone masonry, masonry masonry stone surface pressure waves of different blocks and so on. Irrigation block stones and masonry block stone slope of the lower anti-filtration layer, often due to disappear at the bottom of the foot care riprap caused cushion loss, the formation of a hidden danger. And hidden in the surface is not easy to find, once the hidden dangers, the more serious danger, and endanger people’s lives and property. For example, in 2000, two typhoons attacked the island of Hengsha Island in 2000. They found that the blockage of mortar blocks was serious and some of them caused some break in the dike. However, on the surface of the section, Undamaged How to detect hidden dangers, early prevention is very necessary. for
