Monsoon Claims 432 Lives In HP Landslides

Source: Monsoon Claims 432 Lives In HP; Landslides, Accidents Increasing Due To Widespread Rain & Snowfall Monsoon death toll in Himachal Pradesh climbs to  432 which is considered as the highest in last five years while twelve people have died in last 24 hours, according to the Disaster Management Authority. Widespread rains and snowfall at high altitude passes resulting in a series of landslides, disruption of major roads and National Highways threw life completely  out of gear in Himachal Pradesh, even as temperature dropped significantly in Shimla—the capital city, and Lahaul-Spiti district. Wintry conditions prevailed all over the state on Thursday as result of the rains and snowfall in Lahaul-Spiti valleys. Thick fog engulfing the hills for the past 24 hours created havoc trouble for the travelers which also resulted in several road accidents. Few of these were fatal, others left many people injured due to skidding of the vehicles and mid-way collusions . (Photo Credit- Sanjay Sood) Superintendent of Police Lahaul Spiti Manav Verma told Outlook that it has been raining incessantly. A travel advisory has been issued for the people asking them to avoid journey during next 24 hours . There has been a road disruption near Nehru Kund on Manali Leh road (National Highway no 3) due to landslides. It has been continuously raining at Baralacha La Pass ( 15,922 feet) affecting the mobility of the vehicles on Manali Leh road . Only those vehicles used for essential supplies to Leh are allowed to move as the pass has been very slippery for normal mobility of the vehicles. Tourists are not allowed to take-up their journeys . “There is two to three cms of snow at the Pass” said SP Manav Verma, adding that Lahaul may experience snow much before the normal timing. The biggest advantage, however, remains Rohtang Tunnel [...]

3D Finite Element Analysis of a Contiguous Pile Wall

The development site is located on sloping ground approximately 35 m from a motorway cutting. Due to the sloping topography of the site, cut and fill earthworks are to be undertaken to form a level development plateau upon which a large warehouse is to be built. This will require the construction of a circa 400 m long contiguous pile retaining wall to support the ground along the site’s upslope boundary where ground levels will be reduced by up to 8.4 m. Wall Design A plan showing the arrangement of the piles and the 2.0 m wide by 0.8 m deep capping beam is shown in Figure 1. The main 900 mm diameter piles are 17 m long and are staggered in a zigzag arrangement at 0.25 m offsets either side of the capping beam centerline. Interspersed mid-way between the main piles are 600 mm diameter infill piles. The infill piles are located along the capping beam centerline and are 11 m long. Figure 1: Pile and capping beam arrangement Ground Conditions The ground conditions are summarized in Figure 2 which shows a 2D section perpendicular to the wall alignment at the location where the retained height attains its maximum value of 8.4 m. The succession of strata comprises a veneer of clay-rich Glacial Till overlying Coal Measures bedrock. The Coal Measures bedrock is dominated by siltstone and mudstone and has been divided into three [...]
