Development and initial application of test devices for leakage of earth-rockfill dams

open access: yesYantu gongcheng xuebao, 2023
To accurately simulate the seepage characteristics of earth-rockfill dams during leakage, a test device is developed. The device can precisely control the test variables such as platform slope, water supply discharge, water temperature, etc.

Study on Stability Reduction Characteristics of Earth and Rockfill Dams under Rapid Drawdown Using Fully Coupled Seepage-Stress Analysis

open access: yesAdvances in Civil Engineering, 2022
It can be a great expense to examine individually the stability of earth and rockfill dams on rapid drawdown in civil engineering practice. The aim of this present work is to clarify the safe type on the rapid drawdown among the most common types of ...

Local large deformation between cut-off wall and core wall on deep overburden by meshless method

open access: yesYantu gongcheng xuebao, 2023
As a significant type of dam on deep overburden, the earth core rockfill dam connects the concrete cut-off wall and soil core wall directly, and the "penetration" phenomenon with local large deformation may exist between cut-off wall and core wall due to

Experimental study on strength and deformation characteristics of gravelly soil core materials

open access: yesYantu gongcheng xuebao, 2020
For the earth core rockfill dam, the coordination of the strength and deformation of the dam is a key issue that restricts the dam construction. The deformation of the gravelly soil core materials is large, which leads to the transfer of the load to the ...

Large-scale triaxial test study on wetting deformation characteristics of rockfill materials

open access: yesShuili Shuiyun Gongcheng Xuebao, 2023
The wetting of rockfill material can easily lead to the uncoordinated deformation between it and the core wall, thus causing longitudinal cracks at the top of the dam and endangering the safety of the dam.

The Inversion Analysis and Material Parameter Optimization of a High Earth-Rockfill Dam during Construction Periods

open access: yesApplied Sciences, 2022
Inversion analysis is usually an efficient solution to process the monitoring data of earth-rockfill dams. However, it is still difficult to obtain calculation results that are consistent with monitoring data due to different construction statuses.

Study on safety of a high earth-core rockfill dam considering contact effect between dam and foundation

open access: yesShuili Shuiyun Gongcheng Xuebao, 2019
With a traditional method to calculate the stress and deformation of earth-rock dam, the contact effect between the dam and the bedrock is neglected, which is not consistent with the actual condition.
