STEEL WIRE ROPE SAFETY NET SYSTEMS: A BRIEF HISTORY OF APPLICATION TO ROCKFALL MITIGATION IN THE U.S.

Charles N. Yarnell Sales & Marketing Manager Brugg Cable Products, Inc.

ABSTRACT Rocktall and debris flow can eltfeclively be controlled by the application ot steel wire rope net syslems.

Nearly a half century ago, Brugg Cable Products. Inc. recognized Ihe adtvantages of wire rope netting for preventive snuctures and designed and installed the lirst wire rope safety net system or prevention ol snow avalanches. Field tesling o this net indicaled that it can be altemalively used for protection against rocktall and debris flow. The main objecive of continued development was to make tull use o the Ilexibility of wire rope nening its chief advantage over rigid-type systems. Over the years. numerous tests ot rocktall protection systems have been performed in the factory and field. and a damping device was developed and added. Today, there are a wide variety ot sophisticated protective netting systems available for a multitude of applications. including rocktall mitigation. These systems have been used extensively, our Company having over 1000 systems installed on a worldwide basis. Their introduction into the North American market has been progressing steadily trom coast-to-coast.

A review of the approval, testing, design considerations. locations and performance of U.S. installations ot wire rope saiety nel systems are presented with the hope thal the information may contribule to reducing the dangers of rockfan and other hazards o our transportalion system INTRODUCTION Steel wire rope safely net systems used for rocktatl mitigation evolved from the avalanche protection systems developed to protect Alpine villages in the 1950s. In the U.S., lexible safety nets to drape unstable rock faces, divert falling rock into calchment ditches, or as barrier fences to catch falling rock before entering traffic lanes, have been in-use as a remedial measure for only a few years The basic system corponent, the wire rope safety net. is generally rectangular, although other geometric shapes can be. and have been, manufactured. The availability of a variety of sizes of steel wire rope (and the possibility of weaving in either a rectangular or diagonal manner), allows the designer to optimize the safety net for the particular service loads to be placed upon it. These loads can be either static or dynamic.

which gives two general classifcalions of wire rope safety nel application in rockfall miligation; Slope Protection, and Rocktall Protection Barriers.

SLOPE PROTECTION The steel wire rope safety net. due to ts inherent strength and tlexibility. can be used for draping large unstable rock laces and diverting rock slides. and in doing so. can control larger amounts of debris than previously used chain-link or gabion mesh materials. The increased static load handling capability compared to these other methods, results Irom both the anchorage's capacay (both shear and pull-out strength) as well as the larger diameter. steel wire rope used as a net support rope grid The grid layout can vary from a single horizontal cable across the top of the slope to support the sately nets to a full horizontal and vertical net support rope grid around each safety net. (See Figure 1.)

Most ol te U.S. applications ot wire rope salety nets used or plannecd for slope protection to date, can be lound in the Eastern United States. This may be the result of the limiled rights-of-way along the transportation corridors, which preclude the use ol other mitgation methods. However, wire rope safely nets can equally be used to control rock slopes o great height, such as those lound in te Western Unied States, where the impact of a rockfall would exceed Ihe rating of any barrier or catchmenl area

CONCLUSION A review of the above applications reveal that rock slopes akng the highways are receiving a good bit of atention. There Is a saying: 'Nothing draws attention ike a good big ristake.' Change the last word in the saying to 'accidenr' and the reason for the public interest In highway rock sbpes becomes evident.

Hrmust be remenbered that none of these systems can offer absolute protection. Every instaltation is designed to counter the most probable risks, according to certain criteria and statistical data such as:

position of the object lo be protected, round conditions, steepness of slope, size of rocks, etc. The prevertion of ITprobable extremes requires a disproportionate expenditure, but at reasonable cost It is possble to provide relatively good prolectin and reduce risk lo an acceptable leveL References Cross, Richard H.
