Title: Laminated bamboo lumbers (LBL) - green building materials
Abstract: This report will introduce one kind of green building materials named laminated bamboo lumbers (LBL). Detailed manufacturing process for LBL will be introduced firstly. Then the mechanical performance of LBL will be studied based on tensile tests, compressive tests, shear tests and bending tests results. The strain-stress relationship mode was proposed on the basis of the analysis. Comparison with other building materials will be done as well. In addition, some application examples will be shown in the report.

Title: Progress and development trends on mechanism of water-inrush from seam floor and its reinforcement technique by grouting for lower group coal seams in Northern China typed coalfields
Abstract: The Northern China typed coalfield has a wide distribution in China, the main strata of coal measures is Permo-Carboniferous. Because the strata of coal measures most directly deposited on the strong aquifer of Ordovician limestone, the stratum between lower group coal seam(hereafter, LGCS for short) of Permo-Carboniferous and Ordovician limestone aquifer is very thin, floor water-inrush accidents occurred many times in mining LGCS, most theories of water-inrush from coal seam floor came from mining LGCS. In this paper, firstly, it systematically introduced the history and present situation of researching on mechanism for water-inrush from coal seam floor in China, it clarified the researching processes, from water-inrush coefficient method, theory of original position tension crack and the zero position failure, the theory of strong infiltrating channel, the theory of thin board model, five figures and double coefficients method, the vulnerable index method, the key stratum theory, the view of rock-water-stress relations, the similarity theory method, information theory of floor water-inrush, “Down Three Zones” theory, “Four Zones” theory of coal seam floor, to the theory of preferred plane, etc; secondly, it introduced the development course of boreholes layout for large-area grouting reconstruction the aquifer in coal bed floor, from fan-shaped boreholes opening in underground roadway, directional boreholes opening in underground roadway, to directional boreholes opening on the surface; thirdly, it introduced the application status of geophysical techniques(such as electronic resistivity CT method, detection layer with seismic wave, radio wave penetration tomography, transient electromagnetic, and so on )in exploring the effect of large-area grouting reconstruction the floor of LGCS; fourthly, it pointed out that based on further study the mechanism of water-inrush from coal seam floor, studying the interaction between grout and floor strata of LGCS, using the way of directional borehole opening on the surface to grout reconstruction the floor strata of LGCS, and adopting the comprehensive geophysical techniques to detect and evaluate the water inrush risk of LGCS floor before and after grouting reconstruction will be the development direction of prevention and control water of LGCS floor in the future.

Title: Construction safety in Hong Kong skyscrapers
Abstract: Hong Kong is one of the cities with the highest density and the largest number of skyscrapers. Every year, heaps of the construction workers injured during construction work on sites. In this research projects, we interviewed various stakeholders from construction industry to study the factors which are specific that lead to accidents among skyscrapers work. We will also include a case study that showcase the implications of the latest technology, such as robotics, virtual reality, 3D printing etc on safety performance.
This research paper is supported by University Grant Committee, Faculty Development Scheme, Construction safety index for skyscrapers in Hong Kong: A Multi-criteria decision-making approach (Project Reference No.: UGC/FDS15/E01/15)
