The ancient Kilistra settlement is a natural,historical and cultural heritage site in Central Anatolia(Turkey),which makes it an attractive destination for tourists.However,the settlement located on a hill with steep hillsides has suffered from rockfall events,causing the destruction of some historical buildings.The rockfall risk in the region continues to create a serious danger today for land users and visitors during uncontrolled tourist visits.This paper offers an assessment of rockfall hazard for the ancient Kilistra settlement based on experimental investigation and numerical analyses.For the study,comprehensive field studies were carried out,including the identification of slope profiles,scanline surveys on discontinuities and stability analysis of the slopes.The location and size of the fallen,detached and hanging blocks were also identified.Geomechanical properties of the geological units were determined,and also the rockfall risk rating method was applied for the evaluation of the rockfall hazard risk.Runout distance,bounce height,kinetic energy as well as the velocity of the detached and hanging blocks were determined by using two-dimensional rockfall analyses.Based on the results from the rockfall analyses,possible rockfall-based danger zones have been defined for the ancient Kilistra settlement and its dose vicinity.The results of this study point at an immediate necessity for the installation of support systems.Findings of the study also offer preliminary data for the description of risk administration strategies and also provide scientific contribution to the study of the hazard and risk resulting from rockfall phenomena.

结伴行为和逆行行为是两种常见的骑行方式,容易引起自行车流的局部自组织现象和通行效率下降.为研究结伴行为(包括左右结伴和前后结伴)和逆行行为共存对自行车流运动机理和交通特性的影响,建立同时考虑结伴和逆行行为的自行车流元胞自动机模型.通过仿真实验,分别分析左右结伴和前后结伴与逆行共存对自行车流的影响.研究表明:左右结伴和逆行共存会显著降低自行车流的通行能力、增加旅行时间和降低平均速度;前后结伴和逆行共存仅在高车流密度条件下减少平均速度,且引起自行车流轻微振荡;上述负面影响同结伴尺寸、结伴比例、逆行比例和自行车
