Geological Hazard

Since 1991, we have made gratifying achievements in survey and design, risk assessment, ecological restoration and EPC contracting for geological disaster control projects. We have accomplished the survey, design and deformation monitoring for treatment of landslides, collapse, mud flow and high slopes for the Three Gorges, Xiaodongjiang, Fengtan, Sanbanxi, Huanglongtan and Xiangjiaba hydropower projects, geological disaster risk assessment of construction land and a series of ecological restoration and recovery works for over one hundred hydropower, pumped storage, and wind power projects such as Xiangjiaba, Baishi and Yutang HPPs, Bailianhe, Heimifeng, Meizhou and Qiongzhong PSPS, and Huitengliang and Luhejin wind farms. The successful implementation of the Right Abutment Slope Treatment Project for Huanglongtan Dam and the Newly Added Works for Right Abutment Treatment of Huanglongtan Power Plant in 2011 marked a new breakthrough in EPC contracting for geological disaster control projects and has laid a good foundation for further broadening our business scope and searching new economic growth point. Currently, we have obtained three Class A qualification certificates for survey, design and risk assessment of geological disaster control projects. Through the training in practice, a large number of professional talents have stood out, and that has greatly enhanced our overall strength in geological disaster control.

Photos of major geological disaster control and ecological environment restoration projects we conducted


Pilot greening and treatment project for high and steep slopes of quarry for Shenzhen Airport.
A technology of grooving on rock faces and planting veins was adopted for greening on rock slope surface, and the practice has provided a reference in exposed mountain treatment for Shenzhen Municipality.



Survey and design for hillside geological disaster control project at the back of Jiumen Village, Humen Town, Dongguan City
Paving mud and planting grass sods and bushes in the lattices while cutting the slope to reduce load and ensure slope stability successfully controlled the geological disaster and beautified the environment.

The photo above shows the high cutting slope at Cuijin Road of Longbao District, and the photo below shows the loosened rock mass of the high cutting slope at east section of Linjiang Road of Wuling Town in Longbao District




Design of Xiaonanshan Quarry Treatment Project in Shenzhen
A manner of treatment from top to bottom and layered steps was adopted, following the principle of bushes and shrubs are preferential in combination with vines and grasses. Large-scale safety production of open quarry and timely ecological environment restoration were realized.
