Embodiment 1
[0031] Such as Figure 1 ~ Figure 3 Shown, measure and calculate Sichuan Province Wenchuan County Ginkgo Pinggou debris flow dam breach average width b with the inventive method c value with residual high H d value.
[0032] Ginkgo Pinggou in Wenchuan County, Sichuan Province is located near the epicenter of the 5.12 Wenchuan Earthquake, and there are abundant loose solid materials in the trench due to the impact of the earthquake. At 3 o'clock in the morning on August 14, 2010, a large-scale debris flow broke out under the stimulation of heavy rain, and blocked the Minjiang River to form a debris flow dam.
[0033] (1) Field data acquisition
[0034] On the basis of careful field investigation of Ginkgo Pinggou, 6 factors affecting landslide and debris flow dams are determined through field measurements, that is, the 6 basic data of the dam body and the barrier lake are:
[0035] Dam height H=12m, effective dam length B=117m, internal friction coefficient of materials aro...
Embodiment 2
[0046] Measure and calculate the average width b of the Shiping landslide dam breach in Mao County, Sichuan Province with the method of the present invention c value and residual high H d value.
[0047] Maoxian County, Sichuan Province is located in the upper reaches of the Minjiang River. The Shiping ancient landslide in Nanxin Town in the area has obvious deformation, and cracks appear on the front edge and the back side. Especially affected by the 5.12 Wenchuan Earthquake, the cracks in the slope body were significantly widened, lengthened and increased, and large-scale landslides may occur again, and the Minjiang River will be blocked to form a barrier lake.
[0048] (1) Field data acquisition
[0049] The investigation and measurement were completed at the site of the ancient landslide. According to the exploration data of the slope body and the measurement of the front Minjiang River valley, it is expected to estimate the landslide dam height H = 60m, effective dam le...
