Landslides induced by engineering construction are very common in reality; it is necessary to clarify the causes of landslide failure to avoid similar accidents. A landslide induced by highway construction is taken as a case. Field observations, data collection, and analyses were used to investigate the deformation and causes of the landslide. The failed slope is mostly comprised of gravel soil, there were some shear cracks on both sides of the slope before sliding, and most tensile cracks were connected with shear cracks after sliding. The cut slope of this highway was designed to be protected by prestressed anchor sheet piles. However, in the construction process, the slope in front of the antipiles was removed when the piles were constructed without any anchor cables, which led to the shear damage of a row of anti-slide piles with a 15-meter-long cantilever. Moreover, continuous rainfall over several days aggravated the landslide damage because of increase of the self-weight and degradation of the mechanical parameters of the slope materials. The mechanical and simulation analyses both show that the resistance provided by the cantilever piles was not enough to prevent the force behind the piles. The irrational construction process and rainfall caused the slope failure.

Nanotechnology can be used for design and construction processes in many areas since nanotechnology generated products have many unique characteristics. These characteristics can significantly fix current construction problems, and may change the requirement and organization of the construction process. This paper reviews the basic concept of nanotechnology, different types of nanomaterial and their manufacturing process as well as the applications of nanotechnology in different fields such as concrete, pavement engineering, construction materials. Use of nanotechnology is found to offer high performing and efficient materials. Specific application areas include water and waste water treatment, construction materials etc. The use of nanotechnology in civil engineering is still in infancy stage. The production methods, pollutions caused to human health, manufacturing difficulties, performance are the issues to be addressed in order to use the nanotechnology in civil engineering.

Cannabis Social Clubs (CSCs) are a nonprofit model for the supply of cannabis originating in Spain. This article aims to provide an overview of current CSC practices in Barcelona, exploring the role played by CSC Federations in shaping them. This analysis draws on 32 semistructured interviews with CSC managers ( n = 15) and with other stakeholders in Barcelona ( n = 17). We build also on field observations at other CSCs based in Barcelona. We found a heterogeneity of CSC practices, some of which were not in line with the self-regulatory codes developed by the CSC Federations. In applying an earlier CSC typology, we identified also country-specific CSC features. While the CSC Federations have contributed to unifying the cannabis movement and made efforts to homogenize CSCs’ practices, in the absence of (government) cannabis regulation, their efforts have to some extent been undermined.

For a country, the industry is a very important system, the embodiment of the country's comprehensive national strength, the country's economic development level and the development of science and technology level has direct impact on industry. The development of chemical industry also has great impetus to the national economic development. The technical requirements for chemical engineering are particularly high. Because of the danger of the chemical itself, safety becomes the first thing to notice in the construction process. In order to prevent the occurrence of danger in the actual construction process, the safety of chemical engineering construction is made, and the effective safety management is the most critical step. A reliable safety management is the guarantee for the smooth construction of the construction, so the early safety management becomes the key to the development of the chemical industry. Chemical engineering is an extremely complex and changeable system, and the kinds of problems involved are very many, which requires the construction personnel to pay more attention to ensure the safety. In order to implement the safety management measures in the process of chemical engineering construction, it is necessary for the management personnel to strictly control the whole construction process. In case of any problem, we should deal with it in a timely manner and pay more attention to the details. We should pay attention to fire prevention, pollution prevention and anti-explosion prevention. Technical personnel should pay more attention to technical problems and eliminate safety hazards. The construction company must also strengthen the personal quality of the project management personnel and other issues. It is necessary to examine personal responsibility and safety awareness and avoid unnecessary losses caused by various construction safety issues to the company[1].

Support Treatment

For the whole process of civil engineering construction, slope support technology is a very key technical point of civil construction. Engineering and technical personnel shall be able to fully ensure the safety and firmness of the foundation structure of the engineering slope by setting up retaining walls or using other slope support treatment techniques, and extend the safe service life of civil engineering. Under this premise, engineering and technical personnel must integrate the technical measures of slope support into the construction process of civil engineering.

The Goodwyn Interfield Pipeline was laid on the Australian North West Shelf, connecting the Goodwyn and North Rankin platforms, in 1993. It is operated by Woodside Energy Limited, and is used to transport hydrocarbon fluid from the Goodwyn and Echo/Yodel fields to the North Rankin A platform, which is connect to onshore processing facilities by the 140 km North Rankin trunkline. This pipeline was expected to self-bury along the majority of its length. After nine years however, some sections of the pipeline have experienced significant self-burial, however, other sections remain exposed. The first part of this paper details the results collected from annual surveys of the pipeline, while the second part looks at modelling the self-burial process. The effect of internal waves is found to be a key driver in the self-burial process.
