Experimental study on the migration of fine grains with seepage in a soil layer

A device for modeling the erosion and re-deposition of fine grains in the soil layer by artificial rainfall was designed. Through experiments, the effects of rainfall intensity and soil thickness on the migration of fine grains were investigated. The changes in grain size distribution with soil thickness under rainfall induced seepage were observed. It is shown that fine grains move downwards in the soil layer with rainfall induced seepage and re-deposit at the lower or middle part of the soil layer to form a thin layer of reduced permeability. Accordingly high pore water pressure forms, and the effective stress and the strength of the soil layer decrease, which can initiate debris flow or landslide

Initial Study on the Movement of Flying Rock during Earthquake

地震可能引发大量的飞石,对生命财产造成严重威胁。针对地震飞石问题进行了初步研究。首先基于刚体运动理论和空气运动学理论建立了飞石的运动模型,考虑了空气阻力、地震加速度等参数的影响;然后通过理论分析获得了地震纵横波同时作用和只有横波作用时的飞石的起动速度、最大运动距离、飞行时间等参数的解析方法。分析结果与汶川映秀镇飞石的实测数据吻合良好。这些研究为今后地震中的飞石危害的预测和防范提供了依据

Experimental and numerical analysis on the responses of slope under rainfall

Rainfall is an important factor to trigger the slope failure such as landslides and debris flows. First, the relationship between rainfall duration with the initiation of debris flow and rainfall intensity was mainly studied by the series tests in a box model. Then, the rainfall induced responses of slopes and the initiation of slope failure were simulated by using the software FLAC2D based on the soil parameters in Weijia Gully, Beichuan County, Sichuan Province. The effects of the slope angle, rainfall intensity, soil parameters on the development of the stress, and pore pressure in the soil of the slope were analyzed. It indicates that largest displacements in the slope are mainly located near the toe. With the increase of the rainfall intensity, the effective stress in the slope decreases and the displacement increases

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
