The jury will be told that Fritzl kept his daughter Elisabeth chained up 24 hours a day for the first nine months of her 24-year imprisonment in the dungeon beneath his house in Amstetten, 60 miles from Vienna.
Elisabeth, then aged 18, was chained by her hands to metal posts behind a bed in the cellar, unable to move more than a few inches from the bed.
He later adjusted the shackles so she could reach as far as the toilet, but she remained constantly chained up for between six and nine months, according to prosecution documents which will be submitted in court.
Chistiana Burkheiser, the prosecutor, will tell the jury that the retired engineer raped his daughter on a daily basis after drugging her and dragging her into the secret purpose-built bunker in August 1984.
He is expected to admit the majority of the charges, but will deny the murder charge, which relates to a baby born in 1996 whose body Fritzl burned in a stove.
The prosecution claim he murdered the baby boy by failing to seek medical help when he became seriously ill, but Fritzl is expected to claim that the child was stillborn.
Fritzl's trial, described by one state official as 'the worst criminal case in Austria's history', is attracting worldwide media attention, with hundreds of reporters from more than 20 countries descending on the small town of St Poelten, around 30 miles from Amstetten, where Fritzl's horrendous crimes were committed.
A small number of protesters gathered outside the court, holding banners saying "Shame on Austria" and "Protect our childen."
The jury will be told that Fritzl began raping his daughter within two days of putting her into the cellar.
The prosecution's indictment describes how Fritzl asked his daughter to go down to the cellar "under the pretence that she should help him to carry a door into his garage".
It states: "After they had put the door in place, he ordered her into his office and made her sit down on a stool. He then drugged his daughter, by putting a narcotic substance into a cloth and then holding it around her mouth and nose. He dragged her into a windowless cellar room, 200sq ft in size, which he had already adapted for this purpose.
"He had equipped it with a double bed, a wash basin, a toilet, a TV, a video recorder, an oven and plastic crockery.
"In the cellar there was no daylight or fresh air. The only opportunity to wash was in a sink, there was no shower. There was also no hot water or heating.
"Just after Elisabeth was locked in the cellar, the accused built a reinforced door, which he then reinforced with additional locks and bolts. The door was opened and closed electronically and only Josef Fritzl himself could do this. Elisabeth was kept behind a barrage of secured doors, with no chance to escape.
"Elisabeth's imprisonment was premeditated; Fritzl had been planning her imprisonment in the dungeon cellar for two to three months before he actually lured his daughter down there."
Fritzl explained away Elisabeth's disappearance by claiming she had run away to join a cult.
"Once in the cellar he chained his daughter up, strapping her arms and tying her hands behind her back with an iron chain, which he then secured to metal posts behind her bed. She had no chance to escape. Her movement was severely restricted. She could only move half a metre either side of the bed. After two days he attached the chain around her waist so she could reach the toilet and wash basin."
After nine months, Fritzl finally relented and removed the metal chains from around his daughter's waist.
But, as the court will hear, this was purely to make it easier for him to use her as his sex slave.
Elisabeth's ordeal finally came to an end last April when her eldest daughter, Kerstin, 19, became seriously ill and Fritzl took her to hospital, leading to questions which quickly unearthed his appalling crimes.
The trial continues.

Josef Fritzl goes on trial March 16,2009. He is charged with multiple crimes including: abuse, incest, rape, false imprisonment, slavery and murder - arising from his 24-year imprisonment and rape of his own daughter, Elisabeth
