浙江黄岩富山地区受新构造运动的影响,经历了节理发育、流水切割与节理扩张,最终发育成山崩地貌景观。该景观资源丰富,具有组合好、规模大、分布广、科考价值高等特点,是迄今发现的华东地区规模最大的山崩地区。根据《旅游资源分类、调查与评价》的国家标准,对该类景观资源单体进行评价与分级以及开发条件分析,认为黄岩富山山崩地貌观资源具有很大的旅游开发价值。旅游开发时应以保护山崩地质遗迹为前提,以凸显山崩地貌景观的主题与特色为关键,以环境的安全性为根本,实施综合开发。 相似文献

The Lochiel Landslip was initiated in August 1974. It was the result of heavy winter rains, but was facilitated by the occurrence of hydrophilic clay interbedded with the quartzitic country rock. Monitoring has shown that whereas most of the minor features within the mass movement have been degraded and subdued, the headwall region remains active. The backing bluff that defines the tension scar has receded between 5 and 10 m during the last decade. The development of fissures some 90 m upslope from the present headwall suggests that this trend will continue. The widening of fissures located laterally and along the hillslope suggests that it too will fail. These changes illustrate the importance of reinforcement mechanisms in landform development. Seepage was facilitated once fissures had formed and the initial slippage left the strata upslope unbuttressed. 相似文献

炎陵山滑坡群成因分析 总被引:1,自引:0,他引:1
炎陵山滑坡群均为土质滑坡,控滑结构面主要为土/岩接触面,原始坡角15°~35°,单个滑体规模为中型和小型,均为强降雨诱发。变形迹象以多级弧型裂缝为主,侧向剪切裂缝亦较发育,滑动大多由坡角向上发展,呈连锁反应。 相似文献

A landslip occurred near the village of Stanton Lees, Derbyshire, UK, in November 2000 following a prolonged period of heavy
rainfall. The slip resulted in the gradual, progressive down-slope movement of a steep embankment that was supporting an existing
gabion retaining wall and a minor road which was subsequently closed to vehicular traffic. This paper describes the site;
the sequence of events leading up to the start of the landslide; an interpretation of the ground conditions and onsite monitoring
data; and the engineering works carried out in order to stabilise the slip and return the road to serviceability. The landslip
occurred due to the superficial deposits moving over the weathered bedrock after the groundwater levels had been elevated
following a prolonged period of heavy rainfall. A stability analysis indicated that the embankment was at a state of limiting
equilibrium and its factor of safety on slope instability was found to be particularly sensitive to fairly minor changes in
the groundwater levels. The remedial works replaced the existing gabion wall with a new cantilevered, bored pile retaining
wall that comprised two rows of piles (600-mm in diameter), which were staggered in plan arrangement. 相似文献
