Sarah Johnston from Nga Taonga Sound & Vision was among over 8,000 people visiting the newly reopened Great Hall at the city's earthquake-damaged Arts Centre last weekend, and she's going to tell us about the connections between the Great Hall and some historic recordings in the sound archives.
The New Zealand Shipping Federation says the government needs to take the resilience of ports seriously as the Kaikoura earthquake has shown the vulnerability of roading - and consider what their role is when auditing them. Annabel Young is the Executive Director of the NZ Shipping Federation. Canterbury University Professor of Geological Sciences Tim Davies, says improving and increasing the transport network through coastal shipping is essential.
A number of field testing techniques, such as standard penetration test (SPT), cone penetration test (CPT), and Swedish weight sounding (SWS), are popularly used for in-situ characterisation. The screw driving sounding (SDS) method, which has been recently developed in Japan, is an improved version of the SWS technique and measures more parameters, including the required torque, load, speed of penetration and rod friction; these provide more robust way of characterising soil stratigraphy. It is a cost-efficient technique which uses a machine-driven and portable device, making it ideal for testing in small-scale and confined areas. Moreover, with a testing depth of up to 10-15m, it is suitable for liquefaction assessment. Thus, the SDS method has great potential as an in-situ testing method for geotechnical site characterisation, especially for residential house construction. In this paper, the results of SDS tests performed at a variety of sites in New Zealand are presented. The soil database was employed to develop a soil classification chart based on SDS-derived parameters. Moreover, using the data obtained following the 2010-2011 Christchurch Earthquake Se-quence, a methodology was established for liquefaction potential evaluation using SDS data. http://www.isc5.com.au/wp-content/uploads/2016/09/1345-2-ORENSE.pdf
What would we do without glue? Well, it’s estimated that each person in U.S.A and the U.K. uses 18.2kgs of glue annually. I’m probably more of a Sellotape/Blu-Tack person myself, but those statistics sound impressive! The development of commercial synthetic … Continue reading →
